Glyph complexity has no effect on the calculations done in the pixel shader and does not change how glyphs are preprocessed. There are no edge cases. If you'd like to see some ridiculously complex fonts get rendered with Slug, check out the 8th page in the demo at sluglibrary.com. Some of those individual glyphs are composed of over 1000 Bézier curves!
