This patch adds gaps between client windows. It is similar to gaps, but contains additional functionality:
- it also adds outer gaps (between the clients and the screen frame), as well as a gap between the master and stack area,
- it adds keybindings to change the gap size at runtime: [Alt]+[-]/[Alt]+[=] to decrease/increase the gap size and [Alt]+[Shift]+[=] to set it to zero.
The configuration variable
gappx contains the default gap size.
