* gtk/Makefile.am (gtk_private_h_sources): Move more text widget
headers into the private header list
* Makefile.am (pkgconfig_DATA): install pkg-config files
* configure.in: add pkg-config files
* gdk-2.0.pc.in, gdk-pixbuf.pc.in, gtk+-2.0.pc.in: pkg-config files
* gtk/gtkwindow.c (gtk_window_read_rcfiles): Invalidate
outstanding icon caches on theme change.
* gtk/gtkiconfactory.h, gtk/gtkiconfactory.c: New icon system. Three
important types:
(GtkIconSource): Specification for creating a pixbuf
appropriate for a direction/state/size triplet from
a source pixbuf or filename
(GtkIconSet): List of GtkIconSource objects that are used to
create the "same" icon (e.g. an OK button icon), and cache for
rendered icons
(GtkIconFactory): Hash from stock ID to GtkIconSet; used to look
up the icon set for a given stock ID. GTK maintains a stack of
GtkIconFactory to search, and applications or libraries can add
additional icon factories on top of the stack
* gtk/gtkrc.h, gtk/gtkrc.c: When loading an RcStyle, parse
the set of GtkIconSource specified for a given stock ID into
a GtkIconSet, and put the GtkIconSet into a GtkIconFactory for the
RcStyle, under the specified stock ID.
* gtk/gtkstyle.h, gtk/gtkstyle.c: Add a virtual function
render_icon used to derive a GdkPixbuf from a GtkIconSource.
This allows people to theme how prelight, insensitive, etc. are
done.
(gtk_style_lookup_icon_set): Look up a stock ID in the list of
icon factories for a style, and return the resulting
icon set if any.
(gtk_style_render_icon): Render an icon using the render_icon
method in the GtkStyleClass.
* gtk/gtkwidget.h, gtk/gtkwidget.c (gtk_widget_render_icon):
Use the style for a given widget to look up a stock ID, get the
icon set, and render an icon using the render_icon method
of the style
* gtk/gtkstock.h, gtk/gtkstock.c: Header with the GtkStockItem type
(contains information about a stock item), the built-in stock item
IDs, and functions to add/lookup stock items.
* gtk/stock-icons/*: Stock icons that come with GTK
* gtk/gtkbutton.h, gtk/gtkbutton.c (gtk_button_new_stock): Returns
a button based on a GtkStockItem
(gtk_button_new_accel): Takes a uline string and accel group, and
installs the accelerator.
* gtk/gtkimage.h, gtk/gtkimage.c: Make this into a generic
image-display widget.
