According to the GLES3 spec, blitting between multisample FBOs with different internal formats should not be allowed. The compatible_resolve_formats function implements this check. Previously it had a shortcut where if the Mesa formats of the two renderbuffers were the same then it would assume the blit is ok. However some drivers map different internal formats to the same Mesa format, for example it might implement both GL_RGB and GL_RGBA textures with MESA_FORMAT_R8G8B8A_UNORM. The function is used to generate a GL error according to what the GL spec requires so the blit should not be allowed in that case. This patch just removes the shortcut so that it only ever looks at the internal format. Note that I posted a related patch to disable this check altogether for desktop GL. However this function is still used on GLES3 because there are conformance tests that require this behaviour so this patch is still useful.
