Paul Davis	0e656f0a13	workaround/hack/fix for cairo pattern gradient space exceeding 2^16 size limit	2013-06-27 10:41:00 -04:00
Paul Davis	57ff5e3198	fix gradient pattern origin translation for time axis view items ... note: the solution is non-obvious, but the obvious one of applying a translational Cairo::Matrix to the gradient caused an exception to be thrown because of a non-invertible matrix.	2013-06-25 20:41:24 -04:00
Paul Davis	41d68e780f	do not trigger visual changes when Fill::set_* methods don't change anything	2013-04-26 14:19:16 -04:00
Paul Davis	96eee9e7a1	change UIConfig to use accessor/setter methods like RCConfig so that ParameterChanged methods can actually be emitted; add variable (over a small range) background shading for all TimeAxisViewItems	2013-04-16 23:46:22 -04:00
Paul Davis	c1df3295c1	virtual Fill:: and Outline:: methods so that Canvas::Items that cache image renderings of themselves can invalidate those caches when colors etc. change; add Item::{begin,end}_visual_change() so that we can notify the canvas more efficiently when *only* visual properties have changed and not the bounding box (probably needs to be used more widely)	2013-04-16 20:38:10 -04:00
Paul Davis	37dd7e952b	add headers to all canvas .cc and .h files	2013-04-15 22:10:18 -04:00
Paul Davis	64d3763652	remove all xml++.h inclusion by canvas implementations	2013-04-15 22:00:13 -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
