> I got stumped looking for a way to specify flip-invariant text.  This
> appears to be an oversight in the SVG definition.  If I define a symbol
> or other re-usable object containing text, and then use that object
> with the transform "scale=(-1,1)", then the text will render backwards.
> There should be a way to declare text to always read in the declared
> orientation (e.g., left-to-right).  The correct way to do this is to
> compute the bounding box of the text based on the text scale, rotation,
> justification, etc., using the innermost transformation matrix, then
> flip and rotate the text within that bounding box such that it is
> rendered left-to-right and has an angle of -90 to 90 degrees.
