	Oops, yesterday's "fix" for #10466 made it even worse :)

	* app/core/gimpdrawable-transform.c: need the 0.5 offset to
	the pixel's center only for INTERPOLATION_NONE, as the LINEAR
	and CUBIC algorithms already know about their errors.

	* app/tools/gimpperspectivetool.c
	* app/tools/gimpscaletool.c
	* app/tools/gimpsheartool.c: some more s/gint/gdouble/ so the
	tools can detect pointer motions again...
