Kristian Høgsberg ee539e58c3 Fall back to fb pixmaps for backing glyph pictures 
GEM pads pixmaps to 512 byte stride and backs them with a kernel side
buffer objects.  We typically don't render out of glyph pictures, so
we're incurring a lot of overhead per glyph by allocating a GEM pixmap
per glyph.  By looking at the usage hint, we can fall back to
fbCreatePixmap for pixmaps backing glyph pictures, which gives us
a nice tight malloced pixmap.  The fast path for text rendering is
compositing from the glyph cache pixmap to the destination, which
shouldn't be significantly affected.

Quick bit of testing:
(firefox-20090601)
    xlib-rgba-before    384512.49:  1.01x
    xlib-rgba-after     389633.94:  1.00x
The difference being within the margin of error for the benchmark.
