commit db242c8af3110d3ed31cea395aa20361d576396b
Author: Falco Girgis <gyr...@gm...>

Manually aligned PVR primitives to 32-bytes (#678)
This is necessary to leverage the "fast" store-queue path for
pvr_prim(), and everyone doing any level of performance work is having
to manually align every single vertex at the time of declaration... time
to fix this in KOS itself like we did for matrix_t.`
1) Aligned all PVR vertex types to 32-bytes.
2) Aligned all PVR header types to 32-bytes.
