|Subject: [PATCH] vanitygaps - adds gaps to layouts
|
|This patch differentiates between inner and outer gaps as well as
|horizontal and vertical gaps.
|
|The logic of these layouts also aims to be pixel perfect by ensuring
|an even split of the available space and re-distributing the remainder
|among the available clients.
