The goal of this patch set is to remove much of the bulky switch statement
based transform code and replace it with matrix multiplication. Hopefully
this will result in a more maintainable pixman renderer due to the removal
of all the special cases for each screen transform.
Functions to decompose an affine transformation matrix into basic operations
are added - these are useful for determining if bilinear filtering should
be enabled, or if video planes can be used.
Oh, and the pixman renderer now supports zooming.
