	* lib/filter.[ch]: start of interface for generalised handling of
	filters.  I have only done code for export filters so far.  I still
	need to do the gui for this, and convert the current SVG and EPS
	filters to the new API.

	* lib/bezier_conn.c (bezierconn_copy): fix up copy operation.  We
	weren't setting the last handle correctly.  It was actually assigning
	to the wrong position in the handles array, so the last handle was
	left as NULL, which caused the segfault.

	* objects/standard/image.c (image_copy): modified routine so that
	it just adds a reference to the DiaImage structure in the new image
	object.  This seems to have cleared up the problems with copying
	image objects.

	* dia.spec: spec file additions from John Gotts.
