Pixman Accessors

[Maarten Maathuis]

If you need accessors somewhere, then you need them everywhere. So the
effect is that you introduce yet another overhead. Perhaps it's
possible to preempt this somehow in the xserver, the problem there
would be that the xserver can never be a 100% sure it's ok to call
pixman without the accessor functions.
