It looks like each time you rotate a random amount and draw text cairo
is creating a new cairo_scaled_font_t and storing it in the recording
surface for the PDF backend. Each scaled font contains a win32 font
object and there is a limit to the number of win32 font objects.

As each different rotation results in a new scaled font, one possible
work around is to use a fixed set of different rotations (eg multiples
of 5 degrees) instead of a different rotation for every character.
