Fix vertical position of PathText

The PathText would always translate to y=0, regardless of what y
was set to. We should obviously get the y coordinate of the shape
*before* translating it into position to find the distance from
the baseline.

This change also updates the example, which had not been updated
to the changed origin of the PathText, and it adds a Lancelot test
for keeping track of the PathText shape rendering.
