crude ice check that probably works well enough in most cases (so far there's just one ucollisions that returns a land pixel - might want to extend that)
As a special exception, FreeType can also be built with the 'makepp'

Note, however. that you will need at least version 1.19 and pass the
option --norc-substitution to have it work correctly.
