Implement GLX_SGI_make_current_read
Discontinue use of the old GetBuffeSize interface. Track both the current read-drawable and the current draw-drawable. After moving some context state to via_rednerbuffer, GLX_SGI_make_current_read can be enabled. The extension works, but the wincopy test prodcues a black window for the destination window. After messing around with the window and looking at the code, I believe the problem is in the handling of buffer swap requests on a drawable that isn't the current draw-drawable.
