6 vertices, (0,1,2) and (0,2,3). use glDrawElements can reuse the shared
vertices.

Zhigang Gong 0dff23d65b glamor: Don't direct call to any gl functions. 
Create a new structure glamor_gl_dispatch to hold all the
gl function's pointer and initialize them at run time ,
rather than use them directly. To do this is to avoid
symbol conflicts.
