Subject: Get DRI drawable from framebuffer object.
In the software rasterization fallbacks, get the __DRIdrawablePrivate
pointer from the driRenderbuffer that is passed in. This eliminates
the need for the mesa_drawable pointer in MGA context structure.
This partially fixes bug #8799. wincopy no longer produces a black
window for the destination window, but it does produce incorrect
results if the destination window is resized.
