[Make RotView compile.
Miikka Koskinen <arcatan@kapsi.fi>**20070522075338
 
 As I'm not a Xinerama user, I'm not sure if rotView should consider only
 hidden workspaces or also visible but not focused workspaces. I thought hidden
 workspaces only would be more logical.

[throttle the exponential expense when many windows are present.

[make mosaic configure windows by name rather than by Window.
David Roundy <droundy@darcs.net>**20070512215644
 Note that this is still pretty flawed.  Often window names change, and the
 layout then stagnates a bit.  Gimp, for example, opens most its windows
 with the same name before renaming them, so you have to hit mod-return or
 something to force a doLayout.  Also, gimp still overrides xmonad regarding
 the size of its main window.  :(
