lavapipe: failing copy_and_blit dEQP tests
Running dEQP with dEQP-VK.api.copy_and_blit.core.blit_image.all_formats.color.2d.*8*_unorm*1*_unorm*_linear
triggers 99 failures (and 44 passes). This is a narrow-ish filter that catch all failures in the dEQP-VK.api.copy_and_blit.core.blit_image.*
tests.
Two observations:
- This only fails for the combination of 2D textures, 8-bit unorm source format, linear interpolation, and unorm destination format with at least one component wider than 8-bit.
- The result images only show issues on blits that have an odd sizes.
