Revision 1384407

Fix Managers tests.  496 tests pass, although 2 seem to have intermittent failures:
DragManager/Spark/DragManager_Squares_spark DragManager_dragCanvasGreen_afterScrolling
StyleManager/SparkStyles/globalSelectors/GlobalStyles_Halotester TextInput_GlobalStyle_compileTime

Used Cyrill's patches: mustella-drag-manager.diff and mustellaDragManagerCursorPatch.diff.  Other patches were not accepted because they were diffs of baselines that SVN couldn't handle, or were attempts to fix tests by adding <Pause> which we want to avoid if possible.
