Doesn't seem to work.  According to the docs, TIFF is one of the possible
HF_TYPEs but when trying to use a tiff image in a height_field I get: Parse
Error: Unknown image type in image_height_at.  The same TIFF image works as
an image_map.

This is also broken for PNG.  It should work in the next beta.
