virtual functions doesn't work, set a color)

2) If implemented in the WM there actually doesn't /have/ to be any visual 
resize grip at all.
A current KDE desktop will likely see Qt4/Gtk+/OOo/FF/+ - some drawing their 
own resize grips... sometimes.
Also with videoplayers (mplayer et al) it's rather "in the way for no reason" 
in most cases (i'd bet you'll in >90% of all cases either use -fs or keep the

(12x12) in the lower right (left) corner of the window is treated "semi-
