How to pan in perspective views so the point under the cursor stays under the cursor.
// GeneralView.h

void ConfigureView_OpenGL( float ViewVolume[7], float ViewToWorld[4][3] );
#ifdef _D3D9_H_
void ConfigureView_Direct3D( FLOAT ViewVolume[7], FLOAT ViewToWorld[4][3],
                             D3DMATRIX& Projection, D3DMATRIX& World );
#endif
