Layers require that drawing methods potentially draw in more than one bitmaps. To handle this this patch offers the following: - move all drawing methods to use Drawable - Drawables are now handled by GcSnapshot since its the one handling the layers - moved Canvas_Delegate.createCustomGraphics to GcSnapshot which does not expose the Graphics2D objects anymore so its draw() methods are the only way to draw. - handles creating layers in GcSnapshot.save() and blitting them in restore() Other changes: - Clean up the create/save API in GcSnapshot - Fixed drawing bitmaps with alpha and other composite modes.
