[Newbies] Centering text in morphic

How can I center text in morphic? I have a RectangleMorph subclass
representing a "tile." I'd like to display a centered string label
within the morph.
My current approach is to just override #drawOn: with:
TileMorph>>drawOn: aCanvas
super drawOn: aCanvas.
aCanvas drawString: 'hi' on: self innerBounds
However, that just always puts the text in the upper-left corner.
(Code is from memory, so I may have got something wrong.)
By "center", I want the baseline-to-max-ascent for the font to be
centered vertically (not the actual height of whatever characters I
have), while the actual width is centered vertically.
Would it be better to use a StringMorph for placing text like this?
I'm afraid I don't yet understand what layout options I'd need to use
to make it work.
Thanks,
- Johann
