Output squashed at certain output widths

[gregorni]

I noticed this issue in Letterpress, where an image gets squashed vertically or horizontally when converting to ASCII. I couldn't really find a patter, different images seem to get squashed at different sizes.

Cube

 I found this image gets especially squashed from the side at sizes above 200.

Phone

 I found this image gets squashed vertically at sizes below 100 and from 130-160, and squashed from the side at sizes above 170.

Could you please add an example of how to recreate the problem directly with artem, as well as run the command with --verbose trace and include its log output here.

I ran it on the Cube image, here's the output.
