Clean up textblobrandomfont.

The middle set of text is generated by rendering into a surface and
then blitting that to the canvas to generate a certain kind of text
generation. However, we are rendering with a -0.05 rotation and using
nearest-neighbor sampling, which produces nasty artifacts unrelated to
text. Changed the sample to render into the surface with the rotation,
and blit back with no rotation.
