	* tools/pdbgen/pdb/image.pdb
	* app/pdb/image_cmds.c
	* app/core/gimpimage.[ch]: reverted changes I did to the image
	unit earlier. As in 2.0, it will continue to not accept pixels.
	This makes the PDB API and the XCF format compatible again and
	fixes bug #142961 (and to some extent bug #137704).

	* app/core/Makefile.am
	* app/core/gimpimage-unit.[ch]: removed these files. The
	convenience accessors defined here aren't commonly used any
	longer.

	* app/display/gimpdisplay.[ch]
	* app/display/gimpdisplayshell.[ch]: added a unit parameter to
	gimp_display_new(). Made "unit" and "scale" properties of
	GimpDisplayShell.

	* app/actions/images-commands.c

	* tools/pdbgen/pdb/display.pdb: changed accordingly. Use the
	display unit where the image unit was used before.
