2006-01-02  Michael Natterer  <mitch@gimp.org>

	* tools/pdbgen/pdb/context.pdb
	* libgimp/gimp.def: added gimp-context-get/set-paint-method which
	get/set the context's paint-info by name. Use these functions to
	stroke with any paint method (still only with its default paint
	options).

	* app/pdb/context_cmds.c
	* app/pdb/internal_procs.c
	* libgimp/gimpcontext_pdb.[ch]: regenerated.
