The shadows usually extend beyond the glyph extents, but sometimes they are 
limited to the glyph extents, and aren’t drawn.

For example, when the user is inputing new characters.

Shadows drawn outside a glyph extent are sometimes not cleared, and they 
accumulate.  For example, put the cursor over a character C, which initially 
had less shadows around it, but after a few blinks, the shadows accumulate:

   .C.
   :C:
   ;C;
   |C|
   #C#
