Modify the TAT and Monarch client to correctly handle SVG origins other than (0,0)

[VenissaCarolQuadros]

Currently, the TAT canvas does not shift if the SVG origin is anything besides (0,0) despite fitting to graphic height and width and makes the viewBox attribute disappear. This made the output of an earlier implementation of the photo-tactile-handler (origin = (0, -y_max)) appear above the canvas.

While this can be forced to fit using setResolution('fit', 'fit'), this involves the use of transforms which the IMAGE-Monarch client does not handle correctly.

The complete resolution of this issue will involve changes to both the TAT by either using transforms or some other mechanism and also the Monarch client to work correctly with transforms.
