Support GUI scaling

[j5155]

I use a 2880x1920 monitor scaled at 200% for a laptop display. MeepMeep currently seems to entirely ignore this scaling; the window size default appears very small, and though I can increase it by changing the arguments to the constructor, I cannot increase the scaling on the grid or the mouse coordinates.
It would be great if MeepMeep supported this scaling so it would run at the right size.
Alternatives:
A argument or configuration option to increase the GUI scaling
Automatically scale based on the set canvas resolution
Proper Wayland support may also fix this issue?

Temporary Workarounds:

Setting the above option to "Scaled by the system" makes MeepMeep work properly, but has the side effect of making all XWayland apps very blurry.
