Martin Gräßlin 7a1fe42be0 Fix uninitialized memory and logic error in PaintRedirector 
The refactoring of Compositor starting with b1739c3 caused some
regressions due to variables in Workspace and Compositor not
being initialized. Furthermore there was a boolean logic error
in PaintRedirector causing the decorations not to paint.
