We were assuming GL_BGRA_EXT was always supported. We now check that it's supported for rendering. We fail if it isn't because this format is specified as "always supported" by the Wayland protocol. We also check if it's supported for reading pixels. A new preferred_read_format function returns the preferred format that can be used to read pixels. This is used by the screencopy protocol.
