	* app/paint/gimppaintcore-stroke.c (gimp_paint_core_stroke,
	gimp_paint_core_stroke_vectors): Save brush pointer before first
	stroke and restore it after. Fixes bug #102162.

	* plug-ins/common/flarefx.c (FlareFX): Use
	gimp_fixme_preview_do_row instead of memcpy. Fixes bug #112042 for
	this plug-in.

	* plug-ins/common/jigsaw.c: Several cleanups.
	(jigsaw_values_changed): New function as a result of the cleanups.
	(jigsaw): Use gimp_fixme_preview_do_row instead of memcpy.
	Together with the fix to flarefx, fixes bug #112042.
	(draw_jigsaw): Warn if passed a NULL buffer (solves the crash
	reported in bug #112012).

	* plug-ins/gimpressionist/orientation.c: Slightly reformatted.
	(create_orientationpage): Modify orientfirst/orientlast instead of
	sizefirst/sizelast in the corresponding adjustments. Fixes bug
	#112061.
