Subject: Get DRI drawable from framebuffer object.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5af5260f3cc6642c16d6b32b3f42693ffd50374b;p=mesa.git

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.
