Do we really have to get the those values by actually rasterizing the
SVG stuff?  I don't think this was the intention of the SVG
specification in OpenType, since rasterization is slow in general.
IMHO, there *must* be a solution that works without rasterization.

Toshiya-san, could you ask on the OpenType mailing list for
clarification?  This is a generic problem that affects all SVG
rendering libraries.
