FormSplit.py
# A FormSplit lets you place its children exactly where you want them
# (including silly places!).
# It does no explicit geometry management except moving its children
# when it is moved.
# The interface to place children is as follows.
# Before you add a child, you may specify its (left, top) position
# relative to the FormSplit. If you don't specify a position for
# a child, it goes right below the previous child; the first child
# goes to (0, 0) by default.
# NB: This places data attributes named form_* on its children.
# XXX Yes, I know, there should be options to do all sorts of relative
# placement, but for now this will do.
