fix crash in glyph-cachels
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-02-03 Ben Wing <ben@xemacs.org>
* frame.c (Fmake_frame):
* glyphs.c:
* glyphs.c (NUM_PRECACHED_GLYPHS):
* glyphs.c (get_glyph_cachel_index):
* glyphs.c (FROB):
* glyphs.c (mark_glyph_cachels_as_not_updated):
* redisplay.c (regenerate_window):
* redisplay.c (redisplay_window):
When creating a frame, call reset_glyph_cachels on the minibuffer
window as well as the root window. Fixes a crash due to other
glyphs (e.g. the gutter glyph) getting in the glyph cachel before
the pre-cached glyphs that are supposed to have fixed indices
(continuation-glyph, truncation-glyph, etc.).
Add a bunch of asserts to make sure that the glyph cachels always
properly contain the pre-cached glyphs.
