[Glamor] [PATCH 0/3] Add the feature for trapezoid render using shader.

[Zhigang Gong]

I just pushed the stable version of large pixmap branch to
git://people.freedesktop.org/~gongzg/glamor for_large_pixmap

Please pull it and try to merge with your latest trapezoid implementation.

For testing purpose, you can uncomment the following macro defined at
glamor_priv.h
#if 0
#define MAX_FBO_SIZE 32 /* For test purpose only. */
#endif

You can choose a proper max fbo size for your cases.

You can refer the glamor_copyarea to see a simple large pixmap support
without
transform + repeat processing. You can see how to clip on the dest pixmap,
and
then do 2nd round clip on source pixmap and thus can split the rendering to
small pieces.

Any question, please let me know. Thanks.
