  Log:
  Bugfix #5034
  
  When using new Shadowbuffer option "Auto clip", the clipping planes could
  become so narrow that sampling code - using ints - could result in
  overflows (sign flip). This especially for small shadow buffers with high
  bias values.
  
  This fix adds an extra check in shadow sampling for such overflows.
