Soft PixelScale on X11/Windows
=======================
.. we sort up end up with the requirement of mapping window-units  <-> pixel-units
taking the monitor viewport layout into account.

X11/Windows: A simple scaling of the window-units position is not suitable due to multiple monitors,
i.e. a window-units gap will be created and fullscreen/spanning coordinates will be wrong.

TODO: Implement seamless conversion of units incl. monitor viewport mapping
- X11, Windows: Recalculate monitor window-units viewport (native is pixels)
- MacOS Recalculate monitor pixel-units viewport (native is 'points', aka window-units)

Impact will be to have the ability to use either pixel- or window-units
for positioning and size and hence be fully platform independent.

Not sure how and when to complete this task and where to cut the line ..
This work asks to be resolved to have a nice solution though.

(Or it is 'Looking for a problem'? Discussion welcome)
