2004-04-15  Michael Natterer  <mitch@gimp.org>

	Get rid of the "current_context" which was in fact just a bunch of
	global variables. Instead, pass the needed context all the way
	from the GUI and the PDB to the core. This is a prerequisite for
	macro recording and generally helps separating the various
	subsystems from each other. Work in progress...

	* app/core/gimp.[ch]: removed member "current_context" and
	gimp_[get|set]_current_context().

	* app/core/gimp-edit.[ch]
	* app/core/gimpdrawable-blend.[ch]
	* app/core/gimpdrawable-bucket-fill.[ch]

	parameters and use the passed context instead of
	gimp_get_current_context().
