I’m trying to describe the "factor" parameter.
According to the reference (i.e. interface), factor can become:
fit broad max auto default
In the source (grph-trf.mk*), there’s also "min".
- "broad" fails with a "missing )", see below.
- I don’t see a difference between "max" and "fit" (both just use the
max height and ignore the max width).
- "min" fills the defined max space ignoring the ration and thus
distorting the image.
- "auto" keeps the ratio and scales the image down into the max space.
- There’s no option that uses the defined space and crops the image into
it; maybe "broad" is meant to do that?

I was expecting to see an operator or ')' but didn't.
