window: (minimize, 0 size, oom) crashes

[NathanSWard]

There are a set of issues:
#170
#899
#1664
#1882
#2018

That all deal with a window crash when either a window is minimized or the size is set the zero.
All of these issues are related so I'm coalescing them into this issue to centralize discussion here :)

There's been talk that the issue lies withing wgpu, so bevy is unable to do anyting currently about it.
However, if there is more information please feel free to post here and update the progress of this crash.

The resizing the window to 0-width/height is fixed by #1409, however minimizing the window still causes a crash on Windows, caused by requesting a 0-width/height texture.

Looks like this can be fixed by this comment I left a while back: #170 (comment). I can look at creating a PR with those changes.

Opened #2300 to fix.
