[ubuntu] Resizing windows in Awesome WM while in a tiled layout

view story

http://ubuntuforums.org – Howdy all, I've been using Awesome for a few months now, and I'm loving it. I'm starting to try to create my own layouts to take advantage of a giant monitor, and I've come up against a bit of difficulty. The awful.layout.suit.tile layout allows you to drag the vertices of the grid around, automatically resizing the tiled windows as it goes. What I'd like to know is whether or not this feature is easy to write into my own layout; is there a simple option to be enabled, or do the window sizes need to be recalculated on the run using a bit of arithmetic? Thanks (Hardware)
