To position the cursor, use the #_MoveTo trap. To draw the string,
use #_DrawChar, #_DrawString, or just do Lisp output to the view
with FORMAT, PRIN1, etc. If you use #_DrawString, remember to convert
a lisp string to a Pascal string using WITH-PSTRS, and remember that
Pascal strings are limited to 255 characters in length. Also, #_DrawString
doesn't do anything for newline characters, and lisp output will
interpret a newline to mean "move to the left edge of the view".
