a hack that breaks less

Bah...
I basically went and recreated my old hack (though it's likely a bit more wrong
this time - I think I didn't get context scaling right).
But this time I think I have an explanation:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms534181(v=vs.85).aspx
the part of interest might be "StringFormatFlagsNoFitBlackBox" description;
if I'm reading it right, if that flag is unset (like by default), the string
needs to be measured and if it slips out of the bounding box, it should at very
least be pushed back (with regard to alignment type) if possible.

As the rectangles passed to GdipDrawString are (after selecting the relevant
font (16pt, AFAICT)) (-2.67, 0, 0, 0) they're treated as unclipped, so to
combine them properly with clip region, they need to be shifted.
