Restore code to paint the background of the text area which was

Mon Jul 17 18:52:38 2000  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkentry.c (gtk_entry_draw_text): Restore code to
	paint the background of the text area which was accidentally
	removed at some point.

	* gtk/gtkrc.[ch] gtk/gtkstyle.[ch] gtk/gtkthemes.[ch]:

	 - Move	most of the functionality from the theme vtable
	   into GtkRcStyleClass and GtkStyleClass. The moved
	   vtable functions were changed a bit in the move to
	   work better in their new home.

	 - Get rid of the engine and engine_data fields from
	   GtkRcStyle and GtkStyle; instead the theme
	   engine derives theme-specific subclasses of GtkRcStyle
	   and GtkStyle

	 - Add extra dlsym() found entry point to themes,
	   theme_create_rc_style().

	* gtk/gtkstyle.c: Copy xthickness, ythickness fields
	in gtk_style_real_copy.

 	* gtk/themes.[ch]: add a function gtk_theme_engine_register_type()
	to register a type associated with an engine. (The engine
	won't be unloaded as there is an instance of the type.)
