Paul Davis	c4f0063a68	make PolyLine use distance_to_segment_squared(), and add separate (null, for now) method Curve::covers(Duple) because the math there needs to be different, maybe	2013-12-09 17:24:34 -05:00
Paul Davis	6473cc7cb4	drop use of bounding box to determine whether an item covers a point; add Item::covers(Duple const&) ... Default implementation for Item still uses bounding box, but specializations for Arc (Circle), Polygon, Line and PolyLine have been added	2013-11-04 11:56:10 -05:00
Paul Davis	37dd7e952b	add headers to all canvas .cc and .h files	2013-04-15 22:10:18 -04:00

Paul Davis	84fb0a8dce	remove all XML related API from canvas. it may have been useful during development, but it is just a distraction - we will NEVER be saving or restoring canvas state via XML or any kind of serialized state	2013-04-15 21:57:08 -04:00
Paul Davis	aaea166135	initial commit of hand merging, plus getting "ancient" waf script to work correctly	2013-04-04 00:32:52 -04:00
