Enable HW dithering in a few key places (#4541) * Enable HW dithering on supported devices (Clara HD, Forma; Oasis 2, PW4) * FileManager and co. (where appropriate, i.e., when covers are shown) * Book Status * Reader, where appropriate: * CRe: on pages whith image content (for over 7.5% of the screen area, should hopefully leave stuff like bullet points or small scene breaks alone). * Other engines: on user-request (in the gear tab of the bottom menu), via the new "Dithering" knob (will only appear on supported devices). * ScreenSaver * ImageViewer * Minimize repaints when flash_ui is enabled (by, almost everywhere, only repainting the flashing element, and not the toplevel window which hosts it). (The first pass of this involved fixing a few Button instances whose show_parent was wrong, in particular, chevrons in the FM & TopMenu). * Hunted down a few redundant repaints (unneeded setDirty("all") calls), either by switching the widget to nil when only a refresh was needed, and not a repaint, or by passing the appropritate widget to setDirty. (Note to self: Enable *verbose* debugging to catch broken setDirty calls via its post guard). There were also a few instances of 'em right behind a widget close. * Don't repaint the underlying widget when initially showing TopMenu & ConfigDialog. We unfortunately do need to do it when switching tabs, because of their variable heights. * On Kobo, disabled the extra and completely useless full refresh before suspend/reboot/poweroff, as well as on resume. No more double refreshes! * Fix another debug guard in Kobo sysfs_light * Switch ImageWidget & ImageViewer mostly to "ui" updates, which will be better suited to image content pretty much everywhere, REAGL or not. PS: (Almost :100: commits! :D)
