Icon-O-Matic: Remove "using namespace" from header

Putting a "using namespace" statement (_USING_ICON_NAMESPACE in this
case) in a header file causes all source files that include that
header to use that namespace, regardless of whether they actually
wanted to.

libicon: reorder gradient stops when loading from BMessage

Some files have gradients stops stored in an incorrect order.

Fixes #14210

Icon-O-Matic: replace SVG parser with nanosvg

The parser was based on an old example from agg. NanoSVG is originally
based on the same code, but has lots of bugfixes. So it makes sense
to use it.

Nanosvg revision 25241c5a8f8451d41ab1b02ab2d865b01600d949

Fixes #5955, #8586, #13021.

Icon-O-Matic: Make GradientTransformable a BReferenceable

* Switch to using support/Referenceable.h instead of using an older copy
of this code.
* Make GradientTransformable a BReferenceable and fix #12033.

Compilation fixes for x86_64.

Added quite a few missing components to image:

Enable just enough of the message based format used in Icon-O-Matic to allow
BIconUtils to understand and render it. This makes it possible to use the
HVIFTranslator to also read Icon-O-Matic files out of the box. Will cleanup
now duplicated files next.

* Cleanup in the Gradient department. No fuctional change.
Renamed BGradient::color_step to BGradient::ColorStop
as it's called everywhere else. Also renamed BGradient::gradient_type
to just BGradient::Type. Renamed BGradient::Type() to GetType().
* Simplification of method names in Painter.cpp. Some not yet
complete and yet inactive code to accelerate vertical gradients
(bypassing AGG for this special case).

Moved the gradient_type and color_step structs into the BGradient
class/namespace. Renamed the B_GRADIENT_* types to TYPE_* as the context
is already given.

Patch by Artur Wyszynski:
* Implemented BGradient, BGradientLinear, BGradientRadial,
BGradientDiamond, BGradientConic and BGradientRadialFocus
new Interface Kit classes.
* Implemented all the (AGG-based) backend necessary in
the app_server to render gradients (Painter, DrawingEngine)
* app_server/View can convert a BGradient layout to screen
coordinates.
* Added BGradient methods of the Fill* methods in BView.
* Implemented a test app and added it to the image as a
demo.
* Adopted Icon-O-Matic and libs/icon in order to avoid
clashing with the new BGradient class. Re-use some
parts where possible.

Awesome work, Artur! Thanks a lot. Now a more modern
looking GUI has just become much easier to implement! :-)

TODO:
* Remove the need to have gradient type twice in the
app_server protocol.
* Refactor some parts of the patch to remove duplicated
code (Painter, DrawingEngine).
* Adopt the BPicture protocol to know about BGradients.
* Review some parts of the BArchivable implementation.
