[Mesa-dev] [PATCH 1/4] mesa: implement GL_ARB_draw_indirect

Brian Paul brianp at vmware.com

I just did a quick skim and found a few minor things.

First, the subject might be "mesa: implement GL_ARB_draw_indirect and 
GL_ARB_multi_draw_indirect"

This is a big patch and I think it could have been broken down into 
smaller pieces, but I know it's a PITA to redo.  Next time.

Stray '*' in that sentence.

How about simplifying this to:

    return valid_draw_indirect(ctx, mode,
                               indirect, 4 * sizeof(GLuint),
                               "glDrawArraysIndirect"))

Same as above.
