That's the fix I wanted.
Oddly enough, I never noticed the problem until I started bundling 1.0.0
with my application. Then I had many reports of it. However, I also
started bundling a strip chart widget and it's conceivable that my
earlier simpler plots never needed the font cache.

Thank you. That sounds like precisely what I wanted! I can keep my
application self-contained. Wonderful!
