added new API gimp_drawable_estimate_memsize() and virtual function

Browse Source 
2007-12-04  Michael Natterer  <mitch@gimp.org>

	* app/core/gimpdrawable.[ch]: added new API
	gimp_drawable_estimate_memsize() and virtual function
	GimpDrawable::estimate_memsize() which estimate the memsize of a
	drawable after scaling/resizing.

	* app/core/gimplayer.c: implement the virtual function and take
	the layer mask into account.

	* app/core/gimpimage-item-list.[ch] (gimp_image_item_list_get_list):
	added const qualifiers.

	* app/core/gimpimage-scale.c (gimp_image_scale_check): use the new
	function to correctly estimate the new size instead of scaling the
	drawables' memsizes including all constant parts. Fixes bug #329468.

	* app/gimp-log.[ch]: added IMAGE_SCALE log domain.

	* app/core/gimpimage-scale.c: use it here for debugging output.
