#85 shadow map creation of point lights fails

[Randolf Schultz]

The shadow map creation of point lights fails
(misplaces the camera for the rendering of
the shadow maps) when the point lights use
"from"-values different from the default (0,0,0)
for their position.
Work-around:
Transfer the values from the "from"-values
to the "Translate"-values of the
Transformations-property.
