    kwin: Use the robust access functions
    
    Use glReadnPixels() instead of glReadPixels(), and glGetnUniformfv()
    instead of glGetUniformfv().

    kwin/es: Resolve functions for GL_EXT_robustness

    kwin: Resolve functions for GL_ARB_robustness

    Only the subset of functions available in core contexts is resolved,
    except for glGetnTexImageARB() and glGetnUniformivARB(), which are not
    used by kwin.
    
    Instead of setting the function pointers to NULL when the extension isn't
    supported, kwin provides its own implementations that call the non-robust
    versions of the functions.  This is so callers don't have to check if the
    extension is supported before calling the functions.
