don't unfocus when mouse leaves a window
update README
Sad to see Wayland has no replacement for urgency hint yet.
clarify keyboardfocus vs pointerfocus
draw window borders
Works with scaled/rotated displays too!
factor out scalebox()
May switch to the version from sway if that seems like a good idea at
some point.
configure monitor rotation/reflection
add chvt function
It truly isn't just a window manager anymore :-|
make space for window borders
change cursor during move and resize
simplify move/resizemouse functions
funnel all resizing through resize()
use exit code macros everywhere
