    Query rectangle tex parameters when creating a foreign texture on GL3
    
    Previously when creating a foreign rectangle texture it would ignore
    the passed in texture information and query the texture directly when
    using COGL_DRIVER_GL. However this should also work for
    COGL_DRIVER_GL3. This patch changes it to check the private feature
    flags for the texture querying feature instead of directly checking
    the driver value.
