Clear background when drawing FPS text.
Fix incorect parsing of alpah values when doing color transforms.
Don't apply globaAlpha since it's already taken care of in globalColorTransform.
Allow setting of null globalColorMatrix so that no color transformations are applied, also added some small optimizations to fall back on globalAlpha.
First stab at serialzing all display object roots, including those of mask objects.
