glamor: Add glamor_program based copy acceleration
Paints with textures, using a temporary buffer for overlapping copies
Performs CPU to GPU transfers for pixmaps in memory. Accelerates copy
plane when both objects are in the GPU. Includes copy_window
acceleration too.
v2: Use NV_texture_barrier for non-overlapping copies within the same
drawable
v3: Switch to glamor_make_current
v4: Do overlap check on the bounding box of the region rather than
on individual boxes
v5: Use Eric Anholt's re-written comments which provide a more accurate
description of the code
v6: Use floating point uniform for copy plane bit multiplier. This
avoids an int to float conversion in the copy plane fragment shader.
Use round() instead of adding 0.5 in copy plane. round() and +0.5
end up generating equivalent code, and performance measurements
confirm that they are the same speed. Round() is a bit clearer
though, so we'll use it.
