bgl/BGE: glCopyTexImage2D + bgl.buffer creation error more verbose + dome post_draw (it draw only for the last overlayed scene)

Browse Source 
1) glCopyTexImage2D - www.opengl.org/sdk/docs/man/xhtml/glCopyTexImage2D.xml

2) dome post_draw. Now dome mode can also use scene.post_draw. It only runs for the last scene. It's really useful. I'm working on a nice showcase for this (a dome visualizer for the dome mode running with bgl. In the mean time this is a (lame) example of both working together (the buffer is being copied and draw on top of the window):
