Subject: [PATCH] The 'tilewide' layout is a variant of the standard 'tile'
 layout for dwm. Windows added to the master area will be positioned side by
 side, instead of one on top of the other. This makes better use of screen
 space on ultra wide monitors. The stack area remains identical to the
 original 'tile' layout.
