config: add tweak.damage-whole-window

Browse source 
When enabled, foot will ‘damage’ the entire window, instead of just
the modified/updated rows.

This will force the compositor to redraw/blend the whole window.

This can be used to workaround an issue with fractional scaling in
Gnome, where random thin lines may appear.
