Keeping SSH forwarded X11 apps from opening windows too big for your screen

[foxfirefey]

This may be just a *bit* esoteric, but I found the solution to X11 windows being opened too large for my laptop screen while using ssh -X:

defaults write org.x.X11 wm_limit_size -bool true

Then restart X or do:

killall -HUP quartz-wm
