Stop document windows from shrinking below a usable size, and record the AppKit gaps that TextEditor has found. * DocumentWindowController.j: Implement windowWillResize:toSize: to keep the window at or above provisional minimum dimensions. * WORKLIST.md: Add a work list of the AppKit gaps found by TextEditor, the planned additions to the app and the tests done.
