Fold percentage opacity vs rgba

[forresto]

In the design tips, I thought that fold percentage via opacity meant define stroke colors as RGBA. But I guess that should actually be opacity on the strokes? It might be good to support both (Cuttle can do RGBA but not opacity so far.)

Good idea. This should not be hard to implement.

Cuttle's use of rgba was non-standard for SVG 1.1, oops. Now we output stroke-opacity and it works with OS. :)

But it is standard for SVG 2 so I think it makes sense to support eventually. Probably good to avoid it in your software for now, though. 🙂
