Subject: st/xorg: lots of rendering and xv changes
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=319a588238b4c0c58f8f8807e1143ad79cd8f698;p=mesa.git

st/xorg: lots of rendering and xv changes

extract all the rendering code to xorg_rendedrer, make both exa and xv
share that code. in the process cleanup the rendering code and implement
a lot more of the xv infrastructure.
