Highlights:

	over/dissolve blts using embeded and constant alpha.  No
	separate alpha, no support for non-premultiplied alphas.

	Alpha blended text using over (no saturating add beforehand)

	Recommendation, but no requirement for gamma corrected blending.

	Queries for sub-pixel geometry (R, G, B locations) for ClearType.

They also have alpha-blended cursors.  If anyone feels like taking a stab 
at a spec for those in X, feel free.  The hard part is getting them right 
when the screen supports multiple depths.

They don't have anti-aliased geometric figures.
