Vulkan: Fix rotation of interpolateAtOffset interpolateAtOffset's offset was multiplied by flipXY*rotationMatrix, which is a vector. This was unable to actually apply rotation to the offset. The multiplier is changed to a matrix. Can be tested by running interpolate_at_offset*default_framebuffer tests in deqp gles3.1 together with pre-rotation: ./angle_deqp_gles31_tests --deqp-case=dEQP.GLES31/functional_shaders_multisample_interpolation_interpolate_at_offset_no_qualifiers_default_framebuffer --emulated-pre-rotation=90 Bug: angleproject:5843 Change-Id: I9727371375e999f07463b69153df3fd8b28c2a71 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3183108 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Ian Elliott <ianelliott@google.com> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org>
