Bug 805: Graph/GraphUI TextureSequence Scale: Move Region.COLORTEXTURE_LETTERBOX_RENDERING_BIT to TextureSequence and add enabling/disabling of aratio adjustment + letter-box back-color

TextureSequence color-texture params fetched from Graph VBORegion* and fed into shader.

This allows more flexibility in aspect-ratio adjustment as well as setting a clipping background color for
the added letter-box space.
