2005-09-08  Michael Natterer  <mitch@gimp.org>

	* app/core/gimplayer-floating-sel.c (floating_sel_boundary): if
	the floating selection has no alpha, manually create BoundSegs of
	its outline instead of calling boundary_find() (which creates a
	boundary of the last channel). Fixes bug #145373.

	* app/widgets/gimplayertreeview.c
	(gimp_layer_tree_view_floating_selection_changed): update all
	layer names' text attributes, not only for layers with alpha.
	Fixes layer name display when making a new layer out of a floating
	selection without alpha.
