[virglrenderer-devel] [PATCH 4/6] vrend: Use red with swizzle for luminance formats

Use GL_RED based formats with a swizzle to implement virgl luminance
formats. Since GL_RED is color renderable this patch allows more
operations to be performed on virgl luminance formats.
Fixes:
dEQP-GLES2.functional.texture.mipmap.2d.generate.l8_fastest
dEQP-GLES2.functional.texture.mipmap.2d.generate.l8_nicest
dEQP-GLES2.functional.texture.mipmap.cube.generate.l8_fastest
dEQP-GLES2.functional.texture.mipmap.cube.generate.l8_nicest
dEQP-GLES2.functional.texture.specification.basic_copyteximage2d.2d_luminance
dEQP-GLES2.functional.texture.specification.basic_copyteximage2d.cube_luminance
dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.2d_luminance
dEQP-GLES2.functional.texture.specification.basic_copytexsubimage2d.cube_luminance
