This test ensures that "pixman-renderer: half-fix bilinear sampling on edges" keeps on working. Unlike in the original report wayland/weston#373 , here we use buffer scale 2 instead of output scale 2 to trigger bilinear filter. The effect is the same, the actual resulting image in the failing case is just a little different. This is so that it will be easy to add more viewport screenshooting tests in this program in the future. Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
