[PATCH] [1.7] fb: backport fb changes from master for src window operations.

Sun Dec 20 18:26:26 PST 2009
This rolls up the following commits and also keeps the image_from_pict
API compatiblity. It introduces a new image_from_pict_18 API that is
used by the server leaving the old API alone.
I've rolled this up as I don't want to introduce ABI breaks in bisection.
a72c65e9176c51de95db2fdbf4c5d946a4911695 fb: Adjust transform or composite coordinates for pixman operations
bd567061c8b84b268d9bbb01bc4d8981feefb862 Split fbGetDrawable into fbGetDrawablePixmap and fbGetPixmapBitsData
61335052972a78d67c0ba74f902273b34c63a198 Revert "Fix clipping when windows are used as sources"
071b3c1810d9f2602173acc8578caac20e0b771e Revert "Use IncludeInferiors when copying windows before compositing."
8e640d6b131d2865a9725d8997023865b0ef3d69 Revert "Reserve space for two GC values in copy_drawable()."
