Neil Roberts b52d24c933 Check for GL_EXT_packed_depth_stencil
The GL_DEPTH_STENCIL format for renderbuffers is defined in a separate
extension from GL_EXT_framebuffer_object so we probably shouldn't
being trying to use it unless that extension is advertised. This just
replaces the check for whether the driver is GL for a check for a
private feature flag before trying GL_DEPTH_STENCIL. The private
feature flag is set if the extension is available on GL.
