[igt-dev] [PATCH i-g-t] tests/kms_plane: Add 1 pixel wide visible plane test

Mon Feb 25 13:48:32 UTC 2019
This test creates plane and fb which are 1 pixel wider than
maximum visible size. On both ends are vertical lines, first
plane is positioned at place (0,0) and then (-width,0) and
crc is compared. Then plane is positioned to (-1,0) and
(width-1,0) and crcs are compared again.
This test will skip YUV fb formats.
