What is the reason for CenterPlacement not allowing the upper left corner
be off screen? My brother confronted me today and wanted some video output
to be partly off screen, but centered. I suggested CenterPlacement, but it
didn't work the way we expected. If it is desired to not plcae the upper
corner off the screen, could it be made as an option to not care about
that? Maybe a style that specifies a direction you don't want to be
outside the screen, or just a simple boolean style to turn off the
"I'm not going to make the upper left corner unreachable to you"
protectionism that fvwm uses.
I think that the titlebar is more important than the upper left corner.
Now that specific window were border- and titleless, so he had nothing
that really was in interest at the corner. I recommended him to patch out
the code block limiting CenterPlacment to onscreen upper left corner for
now, while I would investigate the reason for the behaviour.
