+# 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.
