Sets the transformation matrix that will be applied when rendering
with this context.
Note that reported metrics are in the user space coordinates before
the application of the matrix, not device-space coordinates after the
application of the matrix. So, they don't scale with the matrix, though
they may change slightly for different matrices, depending on how the
text is fit to the pixel grid.
