GLX: fix context render type queries
Querying the GLX_RENDER_TYPE of a GLX context via glXQueryContext will currently return the render type of the context's FB config, which is a bitmask of GLX_RGBA_BIT / GLX_COLOR_INDEX_BIT / ... values. However, this query should really return the render type that was specified when creating the context, which is one of GLX_RGBA_TYPE / GLX_COLOR_INDEX_TYPE / .... To enable this, save the render type when creating a new context (defaulting to GLX_RGBA_TYPE if unspecified), and then include this value in the context attributes sent to clients.
