# Allow other modules to install data handlers for arbitrary types.
#
# Handler must return a tuple (obj, buffer, buffer_len) of types
# (PyObject, Long, Int).
#
# Look at the C code for details of exactly what happens.
#
# The 'obj' PyObject will be stored in the data set until
# set to something else or the data set is destroyed.
#
# You must take responsibility for life of the obj and ensure
# that the buffer and buffer_len do not change unless
# you call set_points() again before they are used.
