Description
What is the matrix in:
contextPrototype.getCoords_
This is a 3 x 3 matrix, where the passed x and y are used to obtain the coordinates used for the text, but I just don't understand what is going on?
I'm trying to figure out why the coordinates returned by the module do not match those I see in GIMP, can anyone help?

Read pdfcanvas.js around contextPrototype.getCoords_ and trace how its 3 x 3 matrix is used with the supplied x and y values. Done would be a clear explanation of the coordinate transformation and how its output relates to the coordinates shown in GIMP.
