Really? It's not as if your computer has anything better to do.
Again: battery. Many of us are laptop users.
The OP included a link to his project - it's not a screensaver.
That was entirely my fault, sorry. I have no idea where I got the
idea it was for a screen saver. I did not follow the link. In my
defense, a better description of the application's requirements
would've helped in determining a course.
The original suggestion to measure first then decide still applies
but OpenGL is probably unnecessary since this doesn't appear to be an
editor (ie, it's only displaying).
Quincey's suggestion to cache is right on the money: draw it with
bezier paths once, then only display the finished product as PDF data.
You could even separate it out into different 'overlays' for each
'thread file'. That minimizes any redrawing that's necessary when
changing the color of a 'thread file'.
Again, sorry for apparently pulling an aspect of the original post
out of my ***. :-D
