        Route WebCLImage::getGLtextureInfo & ::getInfo, through ComputeContext.
        Issue #132

        Reviewed by NOBODY (OOPS!).

        Route the opencl API calls clGetImageInfo and clGetGLTextureInfo via ComputeContext.
        Validation of flags done by WebCLImage only to avoid  compute*ToCL API in
        ComputeContext.

        No new tests.
