#255 gerbv fails to display logo.

[Roger Wolff]

I've been using gerbv for quite a while now to verify my fabrication files before submitting them.
Today I noticed that on a design my logo was missing. I spent quite a few hours replacing the logo, updating libraries etc etc.... only to find out that the JLCPCB gerber viewer DOES see my logo on my PCB.....
gerbv version 2.7.0
I suspect that the ubuntu standard 18.04 gerbv was working while the ubuntu 20.04 distribution version is not.

Hmm. At "normal" rendering level the logos appear, but the whole gerbv program then becomes excruciatingly slow. Did a default change? Is there some setting that says: ignore features smaller than ... that was increased? It completely ignores my logo now on the fast setting.
