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
Robin Gareus	fee8de9787	Revert "cairo image crash debugging" and "initialize image data" ... This reverts commit dfdb91b429 and commit 188d766757. despite earlier assumptions the code is correct and there is likely a memory corruption elsewhere.	2013-04-20 23:36:13 +02:00

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	fe34485907	add new canvas Image item, with somewhat optimized API for asynchronous, threaded rendering directly into an image buffer suitable for use by cairo as a source surface (currently untested)	2013-04-15 21:40:15 -04:00
