Fix bug: integer underflow in startup phase
When fluxbox comes up some of it's drawables span a 1x1 area. Subtracting from
such small numbers bigger ones always lead to massive problems when 'unsigned
int' are involved:
'button_width' is an unsigned int of '1' (this might be caused by another
issue or on purpose, anyway), subtracting -10 or any other number should
result in something < 0 when in reality an integer underflow happen: max_width
is now MAX_INT-something big. This makes fluxbox crash under certain
circumstances.
This fixes bug #1116.
