Summary: Screen update issues

Initial Comment:
In some cases, the tigervnc server on Linux does not update the screen 
correctly. One case that I can always reproduce is with the Cadence IC design 
software. When a property dialog is opened, there are often thin lines around 
some boxes which are not updated, but where I can still see what was present 
before the dialog opened. A screen redraw fixes the problem. This happens with 
versions 1.1.0 and 1.0.90, independent from the viewer (checked with tigervnc 
viewer and realvnc viewer on Windows XP clients).

Please check the attached example screenshot. Interestingly, the regions which 
are not redrawn are always just one-pixel wide lines.

I seem to recall we had a problem with not tracking window border changes,
but that we ignored it because basically all that used that feature was
twm. Maybe this is the same issue?
