to the SVG specification, and the desktop space, which is the same

except it has the Y axis flipped, and is used to position items on the

canvas. What we want is to change the desktop space to be identical to

the desktop space. _doc2dt determines the mapping between the document

space and desktop space, so we need to change it to the identity

matrix to make those two spaces identical.
