        Attempt to finally fix Smudge tool problems (bug #115057):

	* app/paint-funcs/paint-funcs-generic.h (blend_pixels): added an
	implementation for the non-alpha case.

	* app/paint/gimpsmudge.c (gimp_smudge_start): added back code that
	used to prefill the buffer if the inital area was clipped.
