	* app/tools/gimpeditselectiontool.c (selection_transform_segs):
	Fix off-by-one when dragging the selection. Fixes the last pending
	issue of bug #17904. Use temporary variables for clamp values.

	* app/display/gimpdisplayshell-selection.c
	(selection_transform_segs): Perform the clamping that fixes
	bug #110014 here instead of in the callers. Solves a rare case
	that was not properly handled before.
	(selection_render_points, selection_generate_segs): Remove the
	clamping code from here.

	* app/tools/gimpdrawtool.c (gimp_draw_tool_draw_rectangle): More
	clampings to avoid overflow of 16-bit coordinates.
