mesa: allow GL_UNSIGNED_BYTE type for SNORM reads
OpenGL ES spec states: "For normalized fixed-point rendering surfaces, the combination format RGBA and type UNSIGNED_BYTE is accepted." This fixes following failing VK-GL-CTS tests: KHR-GLES3.packed_pixels.pbo_rectangle.rgba8_snorm KHR-GLES3.packed_pixels.rectangle.rgba8_snorm KHR-GLES3.packed_pixels.varied_rectangle.rgba8_snorm Signed-off-by: Tapani Pälli <[email protected]> https://bugs.freedesktop.org/show_bug.cgi?id=107658 Cc: [email protected] Reviewed-by: Marek Olšák <[email protected]> Tested-by: Andres Gomez <[email protected]>
