bugfix: create the corner pixmaps only once per screen
for each window (windows, menue etc) the initCorners() function of FbTk/Shape.cc was called (which is ok). On each call the corner pixmaps (of the Screen the window belongs to) were created and destroyed the formerly created pixmaps. this is not needed.
