[Mesa-dev] [PATCH 2/2] r600g: Request DWORD aligned vertex buffers.

[Fabian Bieler]

This fixes piglit tests general/draw-vertices and 
general/draw-vertices-half-float.

I only tested this on R700 hardware. Someone with EG hardware should probably 
check if this is necessary there, too, i.e. check if the to aforementioned 
tests fail without this patch.

Note: Some of the test's probes with non-dword aligned strides pass without 
the patch. However, if you examine the rendered image you find that the 
respective triangles are not rendered correctly.
