The icon data in GttkIconInfo->data is currently owned by the
IconThemeDir->icon_data hashtable. However, on e.g. a theme change
blow_themes() destroys the dirs and thus the data, meaning any
outstanding GtkIconInfo points to stale data.
We solve this by adding a refcount to GtkIconData and reffing it
from GtkIconInfo.

Two optimizations for icon cache lookups.
* gtk/gtkiconcache.[hc]:
* gtk/gtkicontheme.c: Remember the directory index for
subdirectories, instead of running over the directory list
again and again.
* gtk/gtkiconcache.c (find_image_offset): Remember the last
chain and try it first; this helps with the the usage patterns
in gtkicontheme.c, where the same icon is queried for a lot
of subdirectories.

Store builtin stock icons in an icon cache, instead of
populating a hash table with pixbufs at startup, to save both
memory and startup time.
* gtk/stock-icons/*: Reorganize the icons in a directory structure
suitable for gtk-update-icon-cache, and rename them to match the
stock ids.
* gtk/gtkiconcache.[hc]: Support non-mmapped icon caches, and
add _gtk_icon_cache_has_icon_in_directory().
* gtk/updateiconcache.c: Support a --source <VARIABLE> argument
to store the contents of the icon cache in a C header.
* gtk/gtkbuiltincache.h: Generated private header which contains
the icon cache for the builtin icons.
* gtk/gtkicontheme.c: Create a GtkIconCache for the builtin
icons, and use that in addition to the hash table whenever
builtin icons are searched.
* gtk/gtkiconfactory.c: Add GTK_ICON_SOURCE_STATIC_ICON_NAME and
use it for static stock ids.
(get_default_icons): Don't add the builtin
icons to the icon theme, just register the stock ids.
(render_fallback_image): Take the fallback image out of the
builtin icon cache.
* gtk/Makefile.am: Remove stock-icons from SUBDIRS and add
the necessary machinery to rebuild gtkbuiltincache.h.
2005-03-15 Anders Carlsson <andersca@imendio.com>
* docs/iconcache.txt:
Update spec.
* gtk/gtkiconcache.c: (find_image_offset),
(_gtk_icon_cache_get_icon_flags), (_gtk_icon_cache_add_icons),
(_gtk_icon_cache_get_icon), (_gtk_icon_cache_get_icon_data):
* gtk/gtkiconcache.h:
Update to be able to fetch pixbuf data and icon metadata.
* gtk/gtkicontheme.c: (theme_lookup_icon), (gtk_icon_info_free),
(icon_info_ensure_scale_and_pixbuf):
Use new cache functions.
* gtk/updateiconcache.c: (foreach_remove_func), (load_icon_data),
(maybe_cache_image_data), (scan_directory), (write_pixdata),
(get_image_meta_data_size), (get_image_pixel_data_size),
(get_image_data_size), (get_single_node_size), (get_bucket_size),
(write_bucket), (main):
Update to write pixbuf data as well as information from .icon
files.

Implement icon theme caching. (#154034, Martijn Vernooij,
caching schema proposed by Owen Taylor, initial implementation
by Anders Carlsson)
* gtk/gtkdebug.h:
* gtk/gtkmain.c: Add a "icontheme" debug flag.
* gtk/Makefile.am (gtk_c_sources): Add gtkiconcache.c
(gtk_private_h_sources): Add gtkiconcache.h
(bin_PROGRAMS): Add gtk-update-icon-cache
* gtk/gtkicontheme.c: Use icon caches if they are available.
Currently, GTK+ uses the cache to get information about the
available sizes, image file formats and .icon files. The
actual image data, and the .icon file contents are not
cached yet.
* gtk/updateiconcache.c: A cmdline utility for generating
icon cache files.
* gtk/gtkiconcache.h:
* gtk/gtkiconcache.c: The glue code to mmap an icon cache
file and manage the information it contains.
