Different viewDirs

Hi,

I tried to determine the current viewing direction from
OpenGL matrices.
When trying both methods voGeometryActions::findCameraPosition and
voGeometryActions::findViewDirection I noticed that the viewDir vector
calculated was different with each method, to be exact the vectors
have opposite directions. Is this a bug or do both methods have differnet
semantics.
