Hash :17d27031 Message :Fix BlitFramebuffer validation for BGRA sources and targets.
It is legal to blit between GL_RGBA8 and GL_BGRA8 sources and
destinations when resolving multisampled renderbuffers. Expand
BlitFramebuffer's validation to handle this case.
Work around a bug in macOS' OpenGL driver querying the number of
samples for GL_BGRA8.
Query GL_MAX_VERTEX_OUTPUT_COMPONENTS on the Core Profile to work
around an error generated on macOS when querying
GL_MAX_VARYING_COMPONENTS.
Expand the BlitFramebuffer tests to cover these cases and start
running them on the OpenGL backend.
