What Every Typesetter Should Know about Renderer Internals

ASS subtitle rendering is seen by many people as some arcane black magic. That's because it is. Luckily, you do not need to understand most of the black magic to learn many meaningful lessons about both the behavior and performance of renderers.

Let's get it over with right away and post the diagram:

A Venn diagram showing two completely disjoint circles. One circle is labeled "What typesetters think is bad for performance." The other circle is labeled "What's actually bad for performance."

Ok, I geeked out, and this is probably more information than you need. But it completely answers the question. Sorry. ☺

Locally, I'm at this commit:

	This is a Python script to extract GNOME/GTK's color scheme and apply it to Wine, so that the themes (approximately) match.

	Instructions:
	1. Set your Gnome theme as you would like it
	2. Run with a command like "python wine_colors_from_gtk.py"
	3. Restart any apps running in Wine. They should match the Gnome theme colors now.
