it allows you to specify the absolute size instead of the relative, by
passing the negative absolute size.

The TileCameraDecorator is intended for rendering a part of a big
screen, i.e. a tile. For antialiasing you want to project the scene to
the exact same projection plane, but with the eye point slightly moved.
This could be achieved with the ProjectionCameraDecorator that allows
you to modify the projection matrices directly.
Hope it helps,
Carsten
