[PATCH 0/3] simplify pixmap create/free hooks

[Jamey Sharp]

During last year's XDS, I started an experiment to see if resource
allocation and freeing could lose the horrible wrap/unwrap boilerplate.
As I recall, I got the idea from something keithp said: Create and Free
hooks could be implemented with callbacks.h instead.

I didn't finish that experiment, but I think these patches are
improvements regardless, and they nicely pave the way for further
cleanups if somebody gets around to it.

The following changes since commit e45a5c9dcf77fc61bfed055f7d7a437741d07315:

  Make GC clientClip always be a region. (2011-09-28 13:27:04 -0700)

are available in the git repository at:

Jamey Sharp (3):
      Have FreePixmap call screen hooks, not the other way around.
      Introduce CreatePixmap, allocating a header and calling screen hooks.
      Move pixmap size limit checking to CreatePixmap, from screen hooks.
