testsuite: Add a test for mask out of bounds effects Inverted alpha masks have an effect on the source, even if the mask doesn't cover the source at all - or worse, is completely clipped out. The GL renderer handles this fine, but Cairo and Vulkan had optimizations that got this wrong. 2023-07-03 18:51:51 +00:00			`clip {`
