This is the first time I've ever submitted a patch to FVWM, so if I've
missed something, please let me know.
The below patch to the CVS sources adds a new style, CenterPlacement.
This style causes FVWM to place new windows in the center of the screen
if they do not request a position using window manager hints or a
geometry specification.
Example usage:
Style * CenterPlacement
The patch includes an update to the man page describing the new style.
I hope people find this useful. I was motivated to code this patch
because my previous method for getting new windows to appear in the
center of the screen was to use FvwmEvent's add_window command, but that
requires that the window appear first before it is moved to the center
of the screen, which is too jumpy visually.
