  icomment: Harald,

            Sorry for the confusion. It looks like I just had to update my fossil
            remote. I pushed the latest changes to
            `tip-754-ttk-composed-pixmaps-cache`. Thanks for getting it all set
            up.

Description
   ttk image element: cache tiled element as a background-free photo

   Compose the element once into an RGBA photo (keyed by size and state)
   and draw it each frame with Tk_RedrawImage, re-compositing against the
   live destination. This replaces the old seed-pixmap composite, which
   baked in the background and so went stale under translucent elements
   and could bleed between widgets sharing a style.

  icomment: Okay, so I implemented TkpPutRGBAImage on Windows (see latest
            ttk-layout-node-cache.diff). With that change plus the layout-node
            caching mechanism, the results seem pretty solid! The gap between
            opaque and transparent is ~ 40ms, and the overall cost is dramatically
            less than without this patch.

            Horizontal and vertical resize are better than diagonal,
            understandably, so the overall performance improvement with this
            change will be really nice on Windows, and Linux given regular usage
            (not the benchmark script). Once macOS can take advantage of the
            caching it will likely see a speedup as well.

            Windows (with TkpPutRGBAImage + cache):

            Diagonal:  - Opaque: resize-bench (diagonal): 52 steps in 6827.6ms
            (131.30ms/step)  - Transparent: resize-bench (diagonal): 52 steps in
            9053.8ms (174.11ms/step)

            Horizontal:  - Opaque: resize-bench (horizontal): 52 steps in 5495.4ms
            (105.68ms/step)  - Transparent: resize-bench (horizontal): 52 steps in
            7858.9ms (151.13ms/step)

            Vertical:  - Opaque: resize-bench (vertical): 42 steps in 3120.4ms
            (74.30ms/step)  - Transparent: resize-bench (vertical): 42 steps in
            4941.8ms (117.66ms/step)

  icomment: Dear Julian,  as you see, it is a question of doing, as nobody took
            the initiative.

            So, a proposal implementation and TIP is required.

            Basically, the implementation is to be copied/removed from Tk and
            moved to Tcl...

            ICU is also used for testing in TCL.

            Thanks for all,  Harald

  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.
