Support panel auto-scaling for HiDPI displays
*Fix scaling of panel widgets, buttons, and the menu bar *Draw grab handles at the ends of the panel *Fix size of _almost_ all included applets *Fix panel snapping coordinates *Down-scale monitor coordinates to support multi-monitors Author: Victor Kareh <[email protected]> Date: Wed Dec 20 14:03:18 2017 -0500
