This commit exports all the rest rendering/drawing functions
to the DDX drivers. And introduce some new pixmap type. For
a pixmap which has a separated texture, we never fallback
it to the DDX layer.

This commit also adds the following new functions:
glamor_composite_rects, glamor_get_image_nf which are needed
by UXA framework. Just a simple wrapper function of miXXX.
Will consider to optimize them next few weeks.

This commit also Fixed a glyphs rendering bug pointed by Chris.
