0ce393f051 likely fix for Canvas::Image positioning under new coordinate/render rules 2013-06-22 14:59:43 -04:00
77f5f4c4bf basically operational switch to canvas drawing coordinates, although text and waves don't work, and redraw areas are too small 2013-06-18 08:23:06 -04:00
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.

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
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
