2001-02-04  Michael Natterer  <mitch@gimp.org>

	* app/Makefile.am
	* app/apptypes.h
	* app/gimpviewable.[ch]: new object. Everything that can have a
	preview will be a GimpViewable. The virtual functions are
	"invalidate_preview", "preview" and "preview_new".

	* app/gimpmarshal.[ch]: new marshaller needed for the viewable.

	* app/gimpdrawable.[ch]
	* app/gimpimage.[ch]: derived from GimpViewable. Removed the
	preview stuff from the public interface.

	Made a single boolean out of GimpImage's "comp_preview_valid"
	array because we have only one copposite preview.

	* app/gimplayer.c: made the preview stuff private.

	* app/gimppreviewcache.[ch]: removed gimp_preview_scale()...

	* app/temp_buf.[ch]: ...and added it as temp_buf_scale() here.

	* app/gimpdrawablepreview.[ch]: is a private method of
	GimpDrawable now.
