Havoc Pennington 86b5c82a97 Re-enable the "find" dialog
2000-10-23  Havoc Pennington  <hp@redhat.com>

        * gtk/testtext.c: Re-enable the "find" dialog

	* gtk/testgtk.c: Add test for gdk_drawable_get_image

	* gdk/gdkwindow.c (gdk_window_begin_paint_region): Fix bug where
	the arguments to gdk_draw_drawable were in the wrong order
	(gdk_window_paint_init_bg): This function was ignoring the
	init_region, instead of clipping to it, so the entire backing
	pixmap was cleared on every begin_paint()
	(gdk_window_begin_paint_region): Hmm, the same list-walking bug
	was in here again, the loop kept using the same GtkWindowPaint
	over and over.
	(gdk_window_begin_paint_region): Fix a bug where we had two
	x_offset instead of x_offset and y_offset

	* gdk/gdkdraw.c (gdk_drawable_get_image): get composite drawable
	before we get the image.
	(gdk_draw_drawable): get the composite before we draw the drawable.
	(gdk_drawable_real_get_composite_drawable): default
	get_composite_drawable implementation that returns the drawable
	itself

	* gdk/gdkdrawable.h (struct _GdkDrawableClass ): Add
	get_composite_drawable virtual function

	* gdk/gdkwindow.c (gdk_window_begin_paint_region): Fix a cheesy
	list-walking bug

	* gdk/x11/gdkdrawable-x11.c (gdk_x11_draw_drawable): Add a hack to
	make this work if the source drawable is a GdkDrawableImplX11
	instead of a public drawable type. This is really broken; the
	problem is that GdkDrawable needs a virtual method get_xid(), but
	of course that doesn't work in practice. Enter RTTI.

	Also, improve mismatched depth message.

	* gdk/gdkpixmap.c (gdk_pixmap_get_image): Implement get_image for
	GdkPixmap

	* gdk/x11/gdkdrawable-x11.c (gdk_drawable_impl_x11_class_init):
	install _gdk_x11_get_image as our implementation of get_image

	* gdk/x11/gdkimage-x11.c (gdk_image_get): Rename to
	_gdk_x11_get_image and export for use in gdkdrawable-x11.c

	* gdk/gdkimage.c (gdk_image_get): Make this just a wrapper around
	gdk_drawable_get_image

	* gdk/gdkdraw.c (gdk_drawable_get_image): call virtual get_image

	* gdk/gdkdrawable.h (struct _GdkDrawableClass ): Virtualize
	get_image

	* gtk/gtktreestore.c (gtk_tree_store_get_node): remove weird
	trailing semicolon after for loop
