BFont: allow loading of user fonts from disk or memory

This patch adds an API call to BFont, called LoadFont, that
takes a string path to a font file. The user fonts are managed
via a new class called AppFontManager that inherits from the base
class FontManagerBase but adds the methods to add and remove user
fonts from disk or memory. There is also a new method called UnloadFont
to remove a user font, but on exit of an app all user fonts should be
automatically cleaned up.

Global/system fonts are managed by the GlobalFontManager, which is
a new class that also inherits from the base class FontManagerBase,
replacing the old "FontManager" class.

A maximum of 128 user fonts may be loaded, and memory fonts
may not exceed 20MB.

There's also an overloaded version of LoadFont that accepts
an area_id and loads the font from memory. A size and offset may
optionally be provided to allow for an area that contains more
than just a font.

Set*UIColor, etc.

The inseparable changes necessary to support live color updating across the
system in a sane, safe, and performant manner.

BView gains:

HasSystemColors()
HasDefaultColors()
AdoptSystemColors()
AdoptParentColors()
AdoptViewColor(BView*)
SetViewUIColor(color_which, float tint)
SetHighUIColor(...
SetLowUIColor(...
ViewUIColor(float* tint)
HighUIColor(...
LowUIColor(...
DelayedInvalidate()

BWindow gains a simple helper method:
IsOffscreenWindow()

BMessage gains:

AddColor()
FindColor()
GetColor()
HasColor() * allegedly this API is deprecated, but I implemented it anyway
ReplaceColor()
SetColor()

Previous private ColorTools methods are made public and moved into GraphicsDefs:

mix_color, blend_color, disable_color

These are fully compatible with BeOS dan0 R5.1 methods and are just code cleanup
of BeOS example code under the OpenTracker license.

In addition, four new colors are created:
B_LINK_TEXT_COLOR
B_LINK_HOVER_COLOR
B_LINK_ACTIVE_COLOR
B_LINK_VISITED_COLOR

These changes are documented in their proper user documentation files.

In addition, due to a history rewrite, B_FOLLOW_LEFT_TOP has been defined and
used in lieu of B_FOLLOW_TOP | B_FOLLOW_LEFT and is included in this commit.

On the app_server side, the following has changed:

Add DelayedMessage - a system by which messages can be sent at a scheduled time,
and can also be merged according to set rules. A single thread is used to service the
message queue and multiple recipients can be set for each message.
Desktop gains the ability to add message ports to a DelayedMessage so that
said messages can target either all applications or all windows, as needed.

Desktop maintains a BMessage which is used to queue up all pending color changes
and the delayed messaging system is used to enact these changes after a short
period of time has passed. This prevents abuse and allows the system to merge
repeated set_ui_color events into one event for client applications, improving
performance drastically.

In addition, B_COLORS_UPDATED is sent to the BApplication, which forwards the message
to each BWindow. This is done to improve performance over having the app_server
independently informing each window.

Decorator changes are live now, which required some reworking.

Rename B_COLOR_WHICH_COUNT to kColorWhichCount

Remove dependence on color constants in ServerReadOnlyMemory.

This fixes a maintainance problem where you have to update this otherwise
unrelated file to keep it in sync whenever you add a color constant.

I've added a B_COLOR_WHICH_COUNT constant to the color_which enum which should
be updated to point to the newest color constants as new ones are added. I
reworked ServerReadOnlyMemory to use this constant instead of using to the
current largest color constant directly. If you use B_COLOR_WHICH_COUNT to
refer to a color in your code expect to get unpredictable and nonsensical
results. Most likely you'll get an undefined result which will return black
but don't depend on it.

The net effect of this is that ServerReadOnlyMemory doesn't need to be updated
anymore when new color constants are introduced but will continue to produce
correct results.

Eliminate kNumColors constant, replace it with B_COLOR_WHICH_COUNT

app_server: Added NormalMouse() and ClickToFocusMouse() methods.

* Made FocusFollowsMouse() inline.

* Made the libbe_test environment basically working under Haiku - to actually

worth an 8k price per file that links against libbe.so, so I didn't want to
commit this as is. An alternative to this solution would be to write a
separate application that is responsible for the app_server's window. Comments

* Removed BeOS compatbility of the libbe_test stuff.

* Added a third hinting mode: monospaced fonts only. This is especially helpful
with low resolution devices like the EeePC - small fonts can look pretty bad
when hinting is turned on, and you still have the advantage of hinting for

global hinting setting).
* Added a TODO comment on why having global settings is not what we aim for.

* The DesktopSettings class is now using that to send the new

* The ServerWindow now propagates font changes to its decorator, causing it
to update its drawing. That means changing the bold font in the "Fonts"
preferences application will instantly change all window titles.
* Factored out a _RebuildAndRedrawAfterWindowChange() out of several Desktop
methods, simplifying some code.
* The DefaultDecorator no longer calls _DoLayout() twice (through SetLook()),
but instead calls the new _UpdateFont() method now also called by
FontsChanged(), and SetLook().
* BWindow::GetDecoratorSettings() now also includes "tab frame" BRect with the
exact footprint of the tab, allowing apps to know the size of the tab to
position itself accordingly.
* Automatic white space cleanup.

Patch by Andrej Spielmann (GSoC):
* Simplified the subpixel related methods for the AGG "pixel format" template
interface, the ones for the solid cover simply pass through the existing
methods, so only one subpixel blending function is left which does the actual
work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
implements subpixel anti-aliasing for any generic AGG vector pipelines. It
is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
rotated, sheared or big enough fonts) depending on the global subpixel
setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
to InterfaceDefs.cpp where other such functions live. They are not related
to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
them to the Appearance preflet instead.

All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.

locking problems (instead of debugging the locker class).
* MultiLocker::IsReadLocked() is now only exported with DEBUG mode turned on, as
it only works correctly in this case.
* Made MultiLocker safe against B_INTERRUPTED, ie. it now just tries to lock again
instead of failing for no obvious reason.
* Removed bogus arguments to acquire_sem_etc() in MultiLocker (like B_DO_NOT_RESCHEDULE).
* Applied coding style to MultiLocker.

Changed the way DesktopSettings work:
* Removed the DesktopSettings lock itself - it's not really needed at all,
and causes some trouble with a clean locking design. This may even have
fixed bug #757, at least I couldn't reproduce it anymore.
* There is now a class for read-only access that requires you to have locked
the desktop (either read or write).
* There is now another class LockedDesktopSettings that allows you to set
settings (and only that) - when you're changing the settings, you must not
have read locked the desktop (ie. hold the single window lock). The class
will obtain a write lock, but write locks can be nested.
* Moved SetWorkspacesCount() into the Desktop class.

* Removed the libbe_test target from some applications - this was only to help
developing them under BeOS, and is thus no longer necessary.

* The app_server no longer uses workspace counts internally, but only columns,
and rows.
* set_workspace_count() now uses the logic formerly found in
WorkspacesView::_GetGrid() to determine the layout.

Small cleanup.

Don't crash the app_server if the font couldn't be found. Fixes bug #4149,
though it still has to be investigated why the font style isn't found.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31901 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added a third hinting mode: monospaced fonts only. This is especially helpful
with low resolution devices like the EeePC - small fonts can look pretty bad
when hinting is turned on, and you still have the advantage of hinting for
text editors and the terminal.
* Added a ServerFont::Hinting() method (that currently only evaluates the
global hinting setting).
* Added a TODO comment on why having global settings is not what we aim for.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28837 a95241bf-73f2-0310-859d-f6bbb57e9c96

Actually restore the "dragger" settings. So the system remember your "Show
Replicants" setting after reboot.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28670 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added a Desktop::BroadcastToAllWindows() method that sends all ServerWindows
a message.
* The DesktopSettings class is now using that to send the new
AS_SYSTEM_FONT_CHANGED message to all windows.
* The ServerWindow now propagates font changes to its decorator, causing it
to update its drawing. That means changing the bold font in the "Fonts"
preferences application will instantly change all window titles.
* Factored out a _RebuildAndRedrawAfterWindowChange() out of several Desktop
methods, simplifying some code.
* The DefaultDecorator no longer calls _DoLayout() twice (through SetLook()),
but instead calls the new _UpdateFont() method now also called by
FontsChanged(), and SetLook().
* BWindow::GetDecoratorSettings() now also includes "tab frame" BRect with the
exact footprint of the tab, allowing apps to know the size of the tab to
position itself accordingly.
* Automatic white space cleanup.

app_server was not storing its settings when the workspace count was changed.
As a consequence this setting was lost unless another setting was also altered
that affected the workspace configuration in some way.
Fixes #2849.

Patch by Andrej Spielmann (GSoC):
* Simplified the subpixel related methods for the AGG "pixel format" template
interface, the ones for the solid cover simply pass through the existing
methods, so only one subpixel blending function is left which does the actual
work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
implements subpixel anti-aliasing for any generic AGG vector pipelines. It
is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
rotated, sheared or big enough fonts) depending on the global subpixel
setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
to InterfaceDefs.cpp where other such functions live. They are not related
to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
them to the Appearance preflet instead.

All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.

Patch by Andrej Spielmann (GSOC):
* Extend the app_server protocol by configuration options to turn
subpixel font rendering on/off and also make the glyph hinting optional
(aligning of glyph shapes to the pixel grid).
* Implement the setting in the app_server and also handle the persistency.

App Server now saves/restores ui_color settings.

Also update the ui_color for menu backgrounds, when using set_menu_info.
Update the menu_info neverthless, when setting the ui_color for menu
backgrounds. Fixes bug #550.

Propagate set_ui_color() up to the DesktopSettingsPrivate class.
Still needs code to save the values.
Also needs a way to access them from Decorator::UIColor(), but the DesktopSettings passed to the ctor can't be cached.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23024 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented BDragger::{Show|Hide}AllDraggers() and its backend in the app_server.
This fixes bug #242. The value is currently stored in a separate file.
* Removed some unused codes from ServerProtocol.h.

* Replaced DEBUG MultiLocker with an implementation that actually helps debugging
locking problems (instead of debugging the locker class).
* MultiLocker::IsReadLocked() is now only exported with DEBUG mode turned on, as
it only works correctly in this case.
* Made MultiLocker safe against B_INTERRUPTED, ie. it now just tries to lock again
instead of failing for no obvious reason.
* Removed bogus arguments to acquire_sem_etc() in MultiLocker (like B_DO_NOT_RESCHEDULE).
* Applied coding style to MultiLocker.

Changed the way DesktopSettings work:
* Removed the DesktopSettings lock itself - it's not really needed at all,
and causes some trouble with a clean locking design. This may even have
fixed bug #757, at least I couldn't reproduce it anymore.
* There is now a class for read-only access that requires you to have locked
the desktop (either read or write).
* There is now another class LockedDesktopSettings that allows you to set
settings (and only that) - when you're changing the settings, you must not
have read locked the desktop (ie. hold the single window lock). The class
will obtain a write lock, but write locks can be nested.
* Moved SetWorkspacesCount() into the Desktop class.

save and restore menu and mouse settings, fixes bug 607


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17676 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removed ColorSet, it's no longer needed or used.
* The Decorator are temporarily using ui_color() - this needs to be changed
to use the DesktopSettings (when the decorator stuff gets refactored); right
now, the colors are fixed.
* Added B_WINDOW_TEXT_COLOR, B_WINDOW_INACTIVE_TAB_COLOR, and
B_WINDOW_INACTIVE_TEXT_COLOR to the UI colors, B_WINDOW_TAB_COLOR is no
longer deprecated. Note, however, that not every decorator may use these
colors.
* Removed unused and wrong (ie. hard-coded paths) stuff from ServerConfig.h.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17236 a95241bf-73f2-0310-859d-f6bbb57e9c96

* There is now a server_read_only_memory structure that is placed in a (surprise!)
read-only area shared between the Desktop and all applications.
* Right now, this area only contains the desktop colors, ie. B_PANEL_BACKGROUND_COLOR
etc.; ui_color() no longer needs to ask the server for these colors.
* The ui_colors are now maintained by DesktopSettings, though ColorSet is still there.
* The default colors are now hardcoded once and for everyone in InterfaceDefs.h, ie.
the app_server uses them as well.
* Desktop::Init() can now also return an error (but that is not yet accounted for).
* Cleaned up InterfaceDefs.h.
* Fixed wrong include in moreUTF8.h.

Menu settings are now handled by the app_server. As a result, changing them does something, although they aren't saved to disk yet. 'click_to_open' is not checked anymore, because it was useless anyway, I'll remove it from the Menu preflet too.

The display resolution is now saved and restored. Probably doesn't handle non-default
modes right yet.
The settings are stored in B_USER_SETTINGS_DIRECTORY/system/app_server/workspaces.
They are currently saved as a flattened BMessage - we might want to switch to the
driver_settings format, though.

Reenabled most of the workspaces functionality - the Workspaces window doesn't
show any windows, but everything else seems to work fine.

The font manager now has default fonts for bold/fixed as well - these are now used
in the DesktopSettings as defaults, too (but can be changed there).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14804 a95241bf-73f2-0310-859d-f6bbb57e9c96

Assigned names to "some BLocker"s to aid debugging.
Small cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@14703 a95241bf-73f2-0310-859d-f6bbb57e9c96

* the FontManager is now a looper (but doesn't do anything useful yet).
* moved the system default font functionality into the DesktopSettings class.
* ServerFont::SetStyle() is now a public method.
* Improved font fallback routines: they will never end up without a font if
there is at least one font installed.
* fixed some minor bugs in the DecorManager.
* Decorator now get a DesktopSettings object passed - dunno if that's a good
idea (since we'll have to open the DesktopSettings header), but it works
for now (and something like this is probably needed anyway).
* a clean ServerFont is now set to the system default font - and not to the
(user chosen) desktop default font anymore (since the font manager doesn't
know about that one).
* Improved font directory scanning in the font manager a bit, it's now using
find_directory() instead of hard-coded paths.

Extracted the settings stuff from the Desktop class. If you now need to access
the desktop's settings, you have to do something like this:
DesktopSettings settings(desktop);
settings.SetMouseMode(mode);
The advantage of this is that this object is fully locked, and cannot lead to
corrupted settings anymore. Also, the settings will stay the same until you
delete the object again.
Updated all accesses to use this new API.
Removed no longer used FFM messages.
Implemented AS_{GET|SET}_MENU_INFO for future use.
