* QuickDictLookup, ImageViewer, NumberPicker: Smarter `update` that will re-use most of the widget's layout instead of re-instantiating all the things. * SpinWidget/DoubleSpinWidget: The NumberPicker change above renders a hack to preserve alpha on these widgets almost unnecessary. Also fixed said hack to also apply to the center, value button. * Button: Don't re-instantiate the frame in setText/setIcon when unnecessary (e.g., no change at all, or no layout change). * Button: Add a refresh method that repaints and refreshes a *specific* Button (provided it's been painted once) all on its lonesome. * ConfigDialog: Free everything that's going to be re-instatiated on update * A few more post #7118 fixes: * SkimTo: Always flag the chapter nav buttons as vsync * Button: Fix the highlight on rounded buttons when vsync is enabled (e.g., it's now entirely visible, instead of showing a weird inverted corner glitch). * Some more heuristic tweaks in Menu/TouchMenu/Button/IconButton * ButtonTable: fix the annoying rounding issue I'd noticed in #7054 ;). * Enable dithering in TextBoxWidget (e.g., in the Wikipedia full view). This involved moving the HW dithering align fixup to base, where it always ought to have been ;). * Switch a few widgets that were using "partial" on close to "ui", or, more rarely, "flashui". The intent being to limit "partial" purely to the Reader, because it has a latency cost when mixed with other refreshes, which happens often enough in UI ;). * Minor documentation tweaks around UIManager's `setDirty` to reflect that change. * ReaderFooter: Force a footer repaint on resume if it is visible (otherwise, just update it). * ReaderBookmark: In the same vein, don't repaint an invisible footer on bookmark count changes.
