BUG: This patch makes the interpolation of colors symmetric when rendering a quad. Previously the quad was split in two triangles, and interpolation was not symmetric. Now the quad is split in four symmetric triangles, and colors and texture coordinates are interpolated accordingly. This patch was provided by a support customer.
