	* pixmaps/Makefile.am
	* pixmaps/edit.xpm: new pixmap. "Someone" needs to go over the
	pixmaps one day ;)

	* app/gimpdatafactoryview.c
	* app/gimpdrawablelistview.c: use the new icon.

	* app/floating_sel.c: stupid: the new gimp_layer_get_opacity()
	accessor speaks in normalized [0.0..1.0] values, so the
	floating selection was invisible after blindly using it.

	* app/gimpimage.c: more stupid: a totally useless sanity clamping
	made the composite preview ugly. Fixed.

	* app/tools/tool_manager.c: why the heck did this never crash before:
	don't dereference a NULL GDisplay pointer.
