* 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
