u_blitter: add integer clear support
We need add a new set of fragment shader variants, along with new vertex elements for signed and unsigned clears. The new fragment shader variants are due to the integers values requiring CONSTANT interpolation. The new vertex element descriptions are for passing the clear color as an unsigned or signed integer value. Signed-off-by: Dave Airlie <[email protected]>
