David Robillard	95d82d7a16	An actual tempo line cache (not quite perfect when scrolling left, but miles ahead of the previous one didn't really help at all). ... Tempo line updating done immediately/directly rather than in an idle handler. Looking for feedback how this works for other people, performance wise... Feel-wise, the obvious lag between scrolling and tempo lines being drawn is now gone. git-svn-id: svn://localhost/ardour2/branches/3.0@3799 d708f5d6-7413-0410-9779-e7cbd77b26cf	2008-09-23 22:23:39 +00:00
David Robillard	7c950f279b	Pulled tempo line stuff out into it's own relatively self-contained class. ... Draw tempo lines on time canvas and connect them up all pretty-like to the ruler ticks. Still needs some visual tweaking, but... they draw! Finally! git-svn-id: svn://localhost/ardour2/trunk@2247 d708f5d6-7413-0410-9779-e7cbd77b26cf	2007-08-05 21:31:02 +00:00
