Subject: [PATCH] Supporting xfce4-panel in dwm
We treat the panel as special window which
- never has borders
- never has focus
- always has y=0
- is never shown as active window in the indicators
- is shown on all tags (via config rule)
- is ignored on focusstack (MOD+j, MOD+k)
Which window? "xfce4-panel" - configurable in config.h
