app_server: add picture player for determining bounding box * Add PictureBoundingBoxPlayer, a new player for BPictures. Instead of drawing the picture, it determines an approximate bounding box of its contained drawing operations. * To increase performance, the resulting bounding box is an approximation: it guarantees to always enclose all pixels of the picture, however not necessarily tightly. * PictureBoundingBoxPlayer::Play() gets a DrawState which is the initial state used when playing the picture. The player does not modify this state (it uses a copy internally), so the method is idempotent.
