That implies .. use highest available scale, or default.

In the current situation this would be the best choice!
However, Ardor3D could work w/ the scale
if getSurface[Width|Height]() (pixel units) would be used
for all graphics related operations,
instead of get[Width|Height]() (window units).
The 'windowing operations' still use get[Width|Height]()
hence a scale operation (look it up) must be performed
to convert window units <-> pixel units.
