I suspect that ShieldCursor is mainly intended for internal use by the
toolbox: it can be called by QuickDraw to get the cursor out of the
way before writing to the screen.  (For unknown reasons, QD even does
this when drawing to offscreen bitmaps.  Go figure.)  If you want to
write on the screen without smashing the cursor, use it.  Remember
to account for the height and width of the cursor when you do.

For household use, however, ShowCursor, HideCursor, and ObscureCursor
are all you need.
