add an alpha channel if the src tile-manager doesn't have one. Warn on 

2004-07-07  Sven Neumann  <sven@gimp.org>

	* app/core/gimplayer.c (gimp_layer_new_from_tiles): add an alpha
	channel if the src tile-manager doesn't have one. Warn on
	unsupported type conversions instead of silently doing the wrong
	thing. Fixes bug #145482.

	* app/core/gimpbuffer.c: cosmetics.
