-    These forms handle vertical scrolling of components with a height of 1
-
-    Horizontal scrolling won't work, and scrolling large widgets will fail
-    miserably. It shouldn't be too hard to fix either of those if anyone
-    cares to. I only use scrolling for listboxes and text boxes though so
-    I didn't bother.
