I think either solution is OK. I think getCursorStringVector() is
only used by the system for drawing those Strings (some people's
apps may use it for other things, but you don't need to worry about
that). And drawCursorStringVector() hasn't been modified in a long
time, so you wouldn'y have to update often.

By the way, I really appreciate it your self-reliance in digging
into the system and figuring out a solution to your problem.

Cheers,
Bill
