9df3157dfc big rework of scrolling, horizontal part considered almost 100% done.
Many more changes than I would typically like in a single commit, but this was all very intertwined.
Vertical scrolling using track-stepping still to follow.

58a30da03d use a centripetal catmull-rom curve to smooth ArdourCanvas::Curve
See http://en.wikipedia.org/wiki/Centripetal_Catmull-Rom to understand the benefits of this.

e6849e9c7e "correct" curve drawing (no artifacts during redraw)
Interpolation errors still need addressing.

c29d392b0c tentative intermediate state for ArdourCanvas::Curve 2014-03-04 21:58:17 -05:00
e60933650e remove debug messages, for now 2014-02-28 17:17:00 -05:00
435c3ad47f change implementation of ArdourCanvas::Curve to use GIMP-inspired ideas.
Presmooth with quadratic bezier, then interpolate when rendering. Not finished yet

007e6bb15b remove unneeded extra methods in ArdourCanvas::Curve 2014-02-27 09:22:36 -05:00
88732abd01 change event propagation to be based on parent/child lineage, not z-axis stacking, plus some more alterations to try to get enter/leave working 2013-12-12 10:03:33 -05:00
a631350f93 implement Curve::covers() in a very primitive way (also note: fails for actual spline curves) 2013-12-09 21:03:16 -05:00
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
64d3763652 remove all xml++.h inclusion by canvas implementations 2013-04-15 22:00:13 -04:00
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
7caf517b27 add (bezier) curves to canvas, use for automation lines; fix issue with rectangles missing their upper line segment; more cairo canvas fixes 2013-04-11 22:54:12 -04:00
