Hi, Robert,
Here's a patch for GraphicsWindowX11.cpp to fix support for disabling
resizing of windows. It seems that some window managers are ignoring
the MWM-based code that was there.
I tried to think of a use case that this would break, but I couldn't
come up with any. Still, you might want to give it a once-over to make
sure there isn't some combination of traits that it won't work for.
