Siarhei Siamashka	e43cc9c902	test: safeguard the scaling-bench test against COW ... The calloc call from pixman_image_create_bits may still rely on http://en.wikipedia.org/wiki/Copy-on-write Explicitly initializing the destination image results in a more predictable behaviour. V2: - allocate 16 bytes aligned buffer with aligned stride instead of delegating this to pixman_image_create_bits - use memset for the allocated buffer instead of pixman solid fill - repeat tests 3 times and select best results in order to filter out even more measurement noise	2013-09-07 17:20:09 -04:00
Søren Sandmann Pedersen	1be9208e04	test/scaling-bench.c: New benchmark for bilinear scaling ... This new benchmark scales a 320 x 240 test a8r8g8b8 image by all ratios from 0.1, 0.2, ... up to 10.0 and reports the time it to took to do each of the scaling operations, and the time spent per destination pixel. The times reported for the scaling operations are given in milliseconds, the times-per-pixel are in nanoseconds. V2: Format output better	2013-08-10 11:18:23 -04:00
