gtk2/gdk/gdktypes.h
Owen Taylor caf8ebc6f1 Reference count the fonts used in the text widget. 
Mon Aug 24 18:37:15 1998  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtktext.c: Reference count the fonts used in
	the text widget.

	* gdk/gdk.h gdk/gdkcolor.c: Rename the color allocation
	freeing functions to be more consistent, and more
	convenient; leave the old names in for backwards compatibility.

	* gdk/gdkcolor.c gdk/gdkprivate.h: Reference count the
	allocations in pseudo-color colormaps to greatly reduce
	calls to XAllocColor. Keep a per-colormap hashtable to
	speed up finding if there is an already-allocated matching
	color.

	* gdk/gdkcolor.c: Don't just match read the system colormap
	when the colormap is created, but synchronize our copy
	with the system colormap periodically.

	* gdk/gdk.c gdk/gdktypes.h gtk/gtkentry.c gtk/gtktext.c:
	Change XIM constants names to match GDK conventions

	* gtk/testinput.c: Allow the drawing area to get the focus.

	* gtk/testgtk.c: Change around the Text test to demonstrates
	multiple fonts, use more colors.

	* gtk/gtkwidget.c: Improve gtk_widget_get_colormap()/visual()
	so they work after a widget is unrealized.

	* gtk/gtktext.[ch]: Remove the requirement that the text
	widget be realized before adding text (!) Allocate colors
	ourself, instead of requiring the caller allocate them.
	Allow changing styles to work properly by keeping track
	of the values for a certain property are default or
	set explicitely.

	* gtk/gtkmenu.h: Added some comments.

	* gtk/gtkentry.c: Changes to match XIM constants.

	* gtk/gdk.h gdk/gdkwindow.c: Add gdk_drawable_set_data(),
	for adding keyed data to drawables. (Uses g_dataset
	internally)

	* gdk/gdkpixmap.c: Keep track of the colors we allocate,
	when creating an XPM - store them as user data for the GdkPixmap,
	so we don't leak colors when we create pixmaps from XPM's.

	Allocate memory for color information in large blocks instead of
	as many little pieces.
