Windows-DRI Extension Added For X.Org Server 1.19

In continuation of yesterday's article about Mesa Gets Improved For Running On Windows With Cygwin, the Windows-DRI extension has landed in the X.Org Server code-base.

This is about improving the OpenGL/GLX support on Windows in a similar manner to the X.Org Server on Mac OS X, with the primary benefactor to this being applications running under Cygwin. See yesterday's article for some more details.

As explained in the X.Org Server commit, Windows-DRI opens up "supports requests to enable local clients to directly render GL to a Windows drawable...Windows-DRI can only be useful if we are using WGL, so make an note if WGL is active on a screen."

On top of the 2,000+ lines of code added to Mesa by Jon Turney, the Windows-DRI extension addition by him in the xserver code-base is just short of another thousand lines. This extension will be present in next month's X.Org Server 1.19 release.
