Version 1.2.0

This version attempts to fix a DPI / window-size issue on macOS, in the case that there are multiple displays.

The app loads assume the primary display is the focus, but on changing the resolution with the right-click context menu, it uses the window that contains the mouse to determine resolution/dpi.

WIll be considered pre-release until tested.

THis is Intel-only. No ARM support yet.
