been since long already. This should help aljen reintegrate his gallium branch sooner than later, which after the speed improvment on softpipe made last days will be welcomed, I'll bet ;-) Maybe it's possible to even have both current Mesa Software Renderer add-on *and* Gallium-based SoftPipe one. Will need to actually support renderer selection (in OpenGL preference panel or via a missing OpenGL Kit API), as today the first add-on found is the only one ever selected... git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33282 a95241bf-73f2-0310-859d-f6bbb57e9c96
