QTabBar: enable high dpi moving of a tab
Moving tabs of a QTabBar goes through a temporary QWidget that
captures a "screenshot" of the tab, and then gets moved around.
Unfortunately, that screenshot was not using the devicePixelRatio,
resulting in blurry text and icons. For some reason, setting
the DPR on the pixmap isn't enough -- that causes it to be
drawn twice as big (bug somewhere in Qt styles?).
Work around that by not using the palette, but a simple widget
which draws the pixmap (which also leads to somehow clean code).
