[racket] Slideshow's current-font-size 1-255

I was trying to make a slide with a large symbol on it.

#lang slideshow
 (parameterize ([current-font-size 280])
   (t "\u2623")))

That gives a contract violation, saying that current-font-size isn't
(between/c 1 255).

Why can't we have font sizes larger than 255?

BTW, I am able to get a large pict by scaling (though, then, with rough

 (scale/improve-new-text (t "\u2623") 20))
