The Y-axis in an SVG document points towards the bottom of the page, that is the Y value increases the further down the page 
you go. When positioning items in a maths or physics context however it is more appropriate to have the Y-axis pointing up 
the page like a normal coordinate system. We can provide an affine transformation matrix to a g element's transform 
attribute that flips the Y-axis for its children.

Let the value of the viewBox attribute of the document's SVG element equal "0 0 w h". Suppose we want a coordinate system
whose origin is at the centre of the viewbox and whose Y-axis points up to the top of the page.
