To draw these primitives, we setup the vertex array state, then issue the drawing command. Before, the 'start' vertex was typically zero and we used the vertex array pointer to indicate where the vertex data starts. This patch checks if the vertex buffer offset is an exact multiple of the vertex size. If so, that means we can use zero-based vertex array pointers and use the draw's start value to indicate where the vertex data starts. This means a series of display list drawing commands may have identical vertex array state. This will get filtered out by the Gallium CSO module so we can issue a tight series of drawing commands without state changes to the device. Note that this also works for a series of glCallList commands (not just one list that contains multiple glBegin/End pairs). No Piglit or conform changes. v2: minor fixes suggested by Ian.

Vinson, I posted a patch to mesa-dev to which fixes this and 104746. If you can test too, that'd be helpful.
Fixed with commit 365a48abddcabf6596c2e34a784d91c8ab929918
