[Xorg-driver-geode] Patches for rendering

[Chris Ball]

Hi Frank,

It's better to e-mail patches inline rather than attached, one e-mail
per patch, so that it's easy to comment on specific parts of them.

Just some quick style points on these:

* always use spaces before open braces, e.g.:

+    }else{

becomes

+    } else {

* spaces after keywords, e.g.:

+           if(exaScratch.repeat && (!exaScratch.maskrepeat) && (exaScratch.op == PictOpSrc)){

becomes

+           if (exaScratch.repeat && !exaScratch.maskrepeat && exaScratch.op == PictOpSrc) {

* wrap lines longer than 80 chars, especially comments:

+           /* For the PictOpSrc operation, we need other region to be black out of the blend region */

becomes

+           /* For the PictOpSrc operation, we need other region to be
             * black out of the blend region */

* You should use a short summary for the subject line, and then a
  longer summary for the body of the commit message, and wrap at 80, e.g.:

Subject: [PATCH 7/7] Fix the PictOpOver opeartion. Progressbar,scrollbar and but
ton are displayed ok.
 Convert the source format in lx_prepare_composite if it is not ARGB32 when doing the first pass.
 Add a function lx_do_composite_mask_opover to handle the PictOpOver operation,the first pass is to
 do the src*(alpha of mask), the second pass is to do the src + (1-a)*dest

becomes:

Subject: [PATCH 7/7] Fixes for PictOpOver operation.

* Progressbar, scrollbar and buttons are displayed ok.
* Convert the source format in lx_prepare_composite if it is not
  ARGB32 when doing the first pass.
* Add a function lx_do_composite_mask_opover to handle the PictOpOver
  operation, the first pass is to do the src*(alpha of mask), the
  second pass is to do the src + (1-a)*dest


Thanks for the patches!  Please could you fix the style points up and
re-send, with one e-mail per patch?  git-send-email will send the
patches in this way, if you're able to use that.

- Chris.
