TODO(nico): Cumulative translations in VML are handled

differently than in SVG. While in SVG we specify the translation
|
relative to the original x, y position attributes, in VML the translation
|
is a delta between the last position of the object (modified by the last
|
translation) and the new one.
|
|
In VML the translation alters the position
|
of the object, we should change that or alter the SVG impl.
