	Patch "Remove the 8e extra safety margin in COVER_CLIP analysis" reduced the required image area for setting the COVER flags in pixman.c:analyze_extent(). Do the same reduction in affine-bench. Leaving the old calculations in place would be very confusing for anyone reading the code. Also add a comment that explains how affine-bench wants to hit the COVER paths. This explains why the intricate extent calculations are copied from pixman.c.

2015-04-24	test: Add a new benchmarker targeting affine operations	Ben Avison	1	-0/+436
	Affine-bench is written by following the example of lowlevel-blt-bench. Affine-bench differs from lowlevel-blt-bench in the following: - does not test different sized operations fitting to specific caches, destination is always 1920x1080 - allows defining the affine transformation parameters - carefully computes operation extents to hit the COVER_CLIP fast paths Original version by Ben Avison. Changes by Pekka in v3: - commit message - style fixes - more comments - refactoring (e.g. bench_info_t) - help output tweak Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.co.uk> Reviewed-by: Ben Avison <bavison@riscosopen.org>
