kwin/clients/kwmtheme/kwmthemeclient.cpp
Daniel M. Duley cb69226b40 Use kdrawutil and committing my initial implementation of the kwm theme 
compatible style. This isn't done but currently reads most of the entries. It
requires you use kwinrc and kdeglobals so kthememgr will need to be updated if
you don't want to apply things manually ;-) I also have to add custom cursor
positioning and some other small things. Also, KWM used a bitmap to set the
mask and I do for now as well. This needs to change into regions as it is
*really* inefficent with KWin. For now installing the .desktop for the plugin
is disabled. I will provide some screenshots for the curious when I launch
mosfet.org ;-)
