[xmonad] darcs patch: Decoratione: generate rectangles first, and create win...

Hi, the patch description says it all. Before pushing I would like someone to test it too (I did all my tests here, with the strangest layouts, still I would like to have someone confirm this patch doesn't break anything). The fact of creating the rectangle first means that the decoration state is now: [(Window,Rectangle),(Maybe Window, Maybe Rectangle)] (the maybe stuff being decorations). As a benefit, now we create only decorations for windows that actually need a decoration. This is needed to let Decoration decorate decorated layouts more efficiently: with the previous approach decorating a decorated layout would mean creating decorations for decorations too, and, since decorations wouldn't get e Rectangle, they were hidden at a later time. (I hope my description is clear...;) Andrea Tue Feb 19 13:21:15 CET 2008 Andrea Rossato * Decoratione: generate rectangles first, and create windows accordingly With this patch Decoration will first generate a rectangle and only if there is a rectangle available a window will be created. This makes the Decoration state a bit more difficult to process, but should reduce resource consumption.
