  icomment: The test script now allows testing fully opaque and also transparency.
            Here are current performance metrics with the latest caching patch. As
            is evident here, the caching dramatically improves the speed for both
            fully opaque and transparent image elements. This is without any
            optimization on the blending path, which should of course be subject
            to the profiling runs.

            Linux (before):  - Opaque: resize-bench (diagonal): 52 steps in
            3410.8ms ( 65.59ms/step)  - Transparent: resize-bench (diagonal): 52
            steps in 20413.2ms (392.56ms/step)

            Linux (after):  - Opaque: resize-bench (diagonal): 52 steps in
            1773.3ms ( 34.10ms/step)  - Transparent: resize-bench (diagonal): 52
            steps in 11097.4ms (213.41ms/step)

            Windows (before):  - Opaque: resize-bench (diagonal): 52 steps in
            25325.8ms (487.04ms/step)  - Transparent: resize-bench (diagonal): 52
            steps in 33213.7ms (638.72ms/step)

            Windows (after):  - Opaque: resize-bench (diagonal): 52 steps in
            8587.4ms (165.14ms/step)  - Transparent: resize-bench (diagonal): 52
            steps in 16579.1ms (318.83ms/step)
