[cairo] Notes on cairo/win32

[Jon Smirl]

My understanding of the MS plan is that DirectX is going to be their
new base driver layer and GDI/GDI+ will be phased out over time. The
drawing API will be the dotNet Avalon one. Of course this is going to
take years to happen. Avalon is similar to Cairo and can print.

The shift from a GDI base to DirectX is parallel to the shift from X's
XAA to X on GL. Basing things on DirectX/GL allows access to more
hardware accelerated drawing functions, especially alpha blending.

DirectX 10 has spec'd hardware changes to accelerate drawing of alpha
blended text with subpixel positioning and to increase the speed of
drawing context switches.

The quick solution is to just use Glitz on OpenGL.
