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. Signed-off-by: Zhigang Gong <zhigang.gong@linux.intel.com>
