PR #7080 <https://github.com/openscad/openscad/pull/7080> is intended to improve the usability of the Customizer with some Windows color schemes.  In particular, under Windows with darker accent colors, the existing behavior has group title bar text in black on that dark color, which is difficult or even impossible to read. In addition (though not its primary goal), it improves the behavior when you switch between light and dark mode while the application is running.  There are still numerous gaps in that picture, but it fixes some of them. See the PR for screen shots demonstrating the change. Note that one unintended change is that the Customizer group title bar text is centered, where it was left-aligned.  (No, it does not make any sense at all that this changed; the old behavior appears to be one of the random effects of enabling Qt style sheets.) The fact that the color of the arrow didn't change is known and appears to be a Qt bug. I only just now noticed that the *shape* of the arrow changed. That appears to be another style sheet side effect.  I need to look into whether it's possible to control it without style sheets. Comments solicited. At the moment I am only able to test this on Windows 11.  Testing on other platforms solicited.  I expect that it may or may not make things better on other platforms, but I don't expect it to make things worse.

Because this is low-risk and easily tweaked or reverted, I've gone ahead and merged it.  It should be visible in development snapshots in a day or two. There may be associated changes in other parts of the UI, but I expect them to be similar and desirable.  The overall trend is to do a better job of tracking OS theme settings.
