With the new window decorations resizing was _really_ laggy on my X11
machine.
Before:
- Click on window border (hitbox doesn't work properly, but that's
another issue)
- Drag and resize
- 4-5s nothing happens
- Window is resized
After:
- Click on window border
- Drag and resize
- Window is resized
I'm still not 100% sure on why this happens on my machine and not
Conrad's/Mikayla's, but seems like that GTK_EDGE_CONSTRAINTS atom is
sent when resizing.
The other thing that I can't explain is that we get a `ConfigureNotify`
when resizing, with the right size, but maybe not often enough?
Anyway, for now we'll go with this.
