I've never yet looked at bidi text until now, but it seems that the
proposed implementation fits in well with rtl text.

I'd see two ways at going at this:
* in the msdrawtext functions, you could split the text into
individual lines, compute the exact length of each line and adjust the
starting point of each line before feeding it to the renderer
* have each renderer implement its own text centering

no1 is probably the way to go, I'll have a look to see how complicated
that would be
