Re: gutter fixes

Hm, if the gutter is a window and you unmap the gutter, some subwindow of the frame will get _one_ expose event, which will be easy to check for and throw away since it must be entirely contained in the gutter (that's not 100% error-free, but the gutter's pretty small; I doubt there are going to be many objects that aren't subobjects of the gutter that will pass that test). Then you do all the work on subobjects of the gutter which can generate no more expose events, map the gutter, and Hey Presto! Theoretically, anyway.... IANAXP
