Well, there's a historical basis for this. Reportlab generates PDF,
which is a dialect of Postscript. Postscript uses the Cartesian
coordinate model for its axes. So, in order to have the whole page be
in quadrant 1 where X and Y are both positive, that puts the origin at
the lower left.
You can use scale (by 1 and -1) and transform to turn it into a more
traditional printing model, if you're careful.
