Comment:

 For all these sizes I tried, the fonts are virtually uniform in their
 width and height relative to the picture. A multi-line description wraps
 at the same points at any resolution. so I think you have the relative
 scaling licked.

 However, they are uniformly compressed too narrow at any resolution.
 Attached is a screenshot that shows the narrowed fonts. Perhaps 1.333333
 is factored in one too many times?
