Comment(by kcrisman):

 The error with `e^x` is
 {{{
 MaskError: Cannot convert masked element to a Python int.
 }}}
 but seems to be related to there being something other than linearity
 involved.  Linear functions work, anything with `^` or `**` or `sin`
 doesn't.
 {{{
 --> 154         self._renderer.draw_text_image(font.get_image(), int(x),
 int(y) + 1, angle, gc)
 }}}
 is the problem - it's converting one of the elements, which is supposed to
 be skipped (masked, right?) to an int.
