kwin/clients/modernsystem/modernsys.cpp
Daniel M. Duley 0ae123ceef Cool new Kwin C++ style engine - Modern system :) This uses buttons orignally 
from the KStyle aqua theme - color reduced, converted to bitmaps, and drawn
using the color scheme. The buttons in different color schemes shows why it's
really cool to support dynamic C++ engines as well as pixmap themes ;-) Also
uses a small frame with a resize handle and mac-like (hehe - of course ;-)
drawing for everything else.

Preliminary screenshots with different color schemes are at:
