From Adrian Egli, "i came around reviewing my code, and found now finally a solution to remove the polygon offset issue. as we all know the polygon offset has a different behaviour on different GPU system (ATI, NVidia) and this make the use of
...
polygon offset complicate. so i looked for a solution to remove this offset.
i changed the shader, also the filtering (default: on) use now a correct 3x3 filter:
1 0 1
0 2 0
1 0 1
div: 6
of course a better one would be
1 2 1
2 4 2
1 2 1
div: 16
but this isn't as performant as the simple filter above is. because we need only 5 texture lookups instead of 9, and the result is still good, if you wish we can add a enum to change the pcf filter type once, if there is a need.
testet on NVidia Quatro 570M and on ATI Radeon X1600

From Adrian Egli, "I changed the PSSM shadow map implementation, if we have filtered turned on, it should be now correct. The implementation is more robut on different scene. i tested it on NVIDIA card against a park scene, a chess board and a terrain.
...
unfort. i couldn't test it on any ATI system. may there will be still another problem there. if there are still some artefacts. we should try out better fZOffSet value

Revert the Camera::setInheritanceMask(0x) calls that were added as workaround to a bug introduced by a bug fix to the way the inhertiance mask was handled in CullVisito::apply(Camera&)

From Adrian Egli, "update the PSSM, i did some bug fixes and added new features to move the camera virtual against the view direction by applaying a simple distance factor (a), which is calculated camera eye - camera center distance. and we can move the "light camera" against the light direction (b).
...
(a) some objects behind the camera can cast shadow
(b) object aboive the camera can cast shadow
then i fixed the shadow map orientation, now screen x coordinate alinged which improve the quality"
