Sheriff Chameleotoptor sighed with an air of weary sadness, and then
turned to Doppelgutt and said 'The Senator must really have been on a
bender this time -- he left a party in Cleveland, Ohio, at 11:30 last
night, and they found his car this morning in the smokestack of a British
aircraft carrier in the Formosa Straits.'

 23:07 < matches> 8 hours in the future
 23:07 < matches> I really should fix my system clock
 23:07 < matches> One of these days...
+--- Day changed Mon Sep 01 2014
+17:05 < matches> The wobbly lines on things are irritating me
+17:10 < matches> There doesn't seem to be anything wrong with Bresenham, which means the actual line endpoints are wrong
+17:11 < matches> The GPU does everything from floats and magically they go to the right spot in the buffer
+17:11 < matches> The CPU has to calculate integer pixel coordinates
+17:16 < matches> I need a magnifier I can't see the pixels that are in the wrong spot
+17:16 < matches> I know they are there
+17:21 < matches> ... ok maybe the Bresen Ham was a little past its use by date
+19:48 < matches> The more I try and get these lines to not look dumb, the more convinced I become that glDrawLines is doing something fancy
+19:56 < matches> You end up with wiggles in the line because the end points round to a different pixel to what you end up at by drawing the line
+19:57 < matches> If you make sure you start from where the last line ended, you still get a bend because of the left over error from the last line
+19:58 < matches> ...
+19:58 < matches> Drawing a single line when you know the Bezier is actually a single line is probably going to be less rage inducing than trying to fix this
+21:01 < matches> The Beziers are now classified according to Loop and Blinn
+21:01 < matches> Well
+21:01 < matches> Maybe
+21:01 < matches> It at least knows what lines are
+21:01 < matches> ...
+21:02 < matches> Ok all the ttf beziers are SERPENTINE and LOOP so that's probably wrong
+21:43 < matches> Ah, floating point precision strikes again
+21:43 < matches> That's kind of annoying
+21:47 < matches> But I suppose it's relevant
+21:47 < matches> Unless I'm totally screwing something up
+21:48  * matches adds in arbitrary fabs(x) < 1e-6 checks
+21:58 < matches> On the other hand, if you use DeCasteljau and stop the sub dividing whenever you get to something that classifies as a line, it's actually pretty cool
+21:59 < matches> But if you zoom in too far it starts to get classifications totally wrong
+22:02 < matches> Yeah I have an abstract due in 2 weeks
+22:02 < matches> so screwed
