Gutter updates

This fixes the problem whereby switching the gutter location doesn't work. It also (hopefully) addresses some of SJT's issues with the registration of buffer tabs. andy 2000-10-27 Andy Piper <andy(a)xemacs.org&gt; * gutter.c (Fset_default_gutter_position): default left and right gutters to visible. (calculate_gutter_size): calculate resonable heuristic for left and right gutter sizes. (specifier_vars_of_gutter): change left and right gutter sizes to autodetect. (calculate_gutter_size_from_display_lines): new function. (output_gutter): check for resizing on left and right gutters. (clear_gutter): don't special case top and left gutters. (specifier_vars_of_gutter): use new signature for set_specifier_caching. * glyphs-x.c (x_redisplay_widget): spelling fix. * glyphs.c (specifier_vars_of_glyphs): * menubar.c (specifier_vars_of_menubar): * redisplay.c (specifier_vars_of_redisplay): * toolbar.c (specifier_vars_of_toolbar): * window.c (specifier_vars_of_window): * scrollbar.c (specifier_vars_of_scrollbar): (complex_vars_of_scrollbar): use new signature for set_specifier_caching. * specifier.c (set_specifier_caching): include recompute flag. (recompute_one_cached_specifier_in_window): always recompute if flag set. (recompute_one_cached_specifier_in_frame): ditto. * specifier.h (struct specifier_caching): add recompute flag. 2000-10-24 Andy Piper <andy(a)xemacs.org&gt; * unexcw.c (copy_executable_and_dump_data_section): add new BSS_PAD_SIZE so that we can re-instate a mini-bss. This keeps gdb 5.0 happy. 2000-08-01 Andy Piper <andy(a)xemacs.org&gt; * gutter-items.el (buffers-tab-omit-function): reference buffers-tab-select-visible-buffers. (buffers-tab-filter-functions): new variable, by default uses buffers-tab-selection-function and buffers-tab-omit-function. (select-buffers-tab-buffers-by-mode): invert arguments. (buffers-tab-select-visible-buffers): new function. Invert calling of buffers-menu-omit-invisible-buffers. (buffers-tab-items): rewrite to use buffers-tab-filter-functions. Rewrite docstring. (gutter-buffers-tab-extent): delete. (add-tab-to-gutter): always build a new extent when adding the tabs. (update-tab-in-gutter): make gutter dirty when orientation changes. -------------------------------------------------------------- Dr Andy Piper Principal Consultant, BEA Systems Ltd
