made the default buffer and stock rendering functions public so derived 

2003-03-03  Michael Natterer  <mitch@gimp.org>

	* app/widgets/gimppreviewrenderer.[ch]: made the default buffer
	and stock rendering functions public so derived renderers
	can use them. Renamed gimp_preview_renderer_render_preview()
	to gimp_preview_renderer_render_buffer().

	* app/widgets/gimppreviewrendererbrush.c
	* app/widgets/gimppreviewrendererdrawable.c
	* app/widgets/gimppreviewrendererimage.c: changed accordingly.

	* app/widgets/gimppreviewrenderertextlayer.[ch]: new renderer
	for text layers which always renders the stock icon.

	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h
	* app/widgets/gimppreviewrenderer-utils.c: changed accordingly.
