This is apparantly a problem with the 'pattern' image type (using a pattern
to generate the height-field).  Unfortunately, I don't know exactly what
causes the problems (a bounds issue, I think).  Anyway, I've made the
height-field code a bit more fault-tolerant so that this will no longer
cause a crash.
