More gutter fixes.

This patch fixes some more gutter problems including some nasty redisplay bugs. I also have included motif combo-box support and the window-pixel-column stuff. I have fixed the buffer tab to now group buffers based upon the major mode of the current buffer. You can switch it off by setting buffers-tab-selection-function to nil. Let me know what you think. I will apply this andy or glyphs_changed as if it is the subwindow cache will have been reset. 1999-08-06 Andy Piper <andyp(a)beasys.com&gt; * gui-x.c (button_item_to_widget_value): cope with strings. * glyphs.h: declare global widget functions.
