Re: [PATCH] generalizing redisplay_output_display_block()

I've just completed some more merging... I'll send out a patch later today, but basically toolbar-(x|gtk).c were using some functions directory out of redisplay-(x|gtk).c instead of going thru the common redisplay routines and device methods. Changing them to do this was pretty simple, and I've verified that X & GTK toolbars work as advertised. The big plus is that if someone ports to a new OS and doesn't use native toolbars (which is more difficult), they can just link with this file. I'm attaching the new file if people want to look at it. I'll probably commit the GTK and common code but not futz with the X stuff until I hear from others. I am trying to get as much code between GTK & X shared as possible so that the odds of bitrot are slimmer. I think the event loop is next, then maybe redisplay.
