        [Qt] fast/canvas/webgl/context-attributes-alpha-depth-stencil-antialias.html fails
        https://bugs.webkit.org/show_bug.cgi?id=56825

        Fixes for context attribute handling:
        - Initialize depth and stencil buffer depending on whether they
        are enabled in context attributes.
        - Always enable depth buffer when stencil buffer is enabled.
        - Disable stencil buffer on OpenGL ES 2.0
        - Cleaned up clutter code from initialization. Made code paths
        more sane.
        - Clear mask is now set correctly in reshape().
