	* app/core/gimpscanconvert.[ch]: removed "width", "height" and
	"antialias" from the GimpScanConvert struct and from
	gimp_scan_convert_new(). Removed gimp_scan_convert_to_channel().
	Added "gboolean antialias" to gimp_scan_convert_render().
	Some general cleanup.

	* app/core/gimpdrawable-stroke.c
	* app/core/gimpimage-mask-select.c
	* app/tools/gimpiscissorstool.c: changed accordingly.

	* app/core/gimpdrawable-stroke.c: renamed
	gimp_drawable_stroke_scanconvert_stroke() to
	gimp_drawable_stroke_scan_convert() and removed the "gboolean
	use_mask_bounds" parameter since we can't decide if it's the
	selection's boundary which is stroked. Instead use
	gimp_channel_is_empty() on the selection which will return FALSE
	while the selection is being stroked.

	* app/paint/gimppaintcore-stroke.c: cleanup.

	(gimp_paint_core_stroke_boundary): don't use "gint i" twice.

	(gimp_paint_core_stroke_vectors): no need to manually close a
	closed stroke.
