hello,
 	This is a patch that should fix slow menus.
 	below are benchmarks showing before and after.

-frames 100 -ao none -nosound -benchmark -quiet -menu -menu-startup

The bencharmks above show 5.5x times improvement for the case when menus are 
enabled but not displayed.

This patch is largely untested, but it seems to do the right thing for me.

can folks review it for correctness?

I would be curious how it works for other people who use -dr and menus.

This is the patch, but without any identation
