[vtk-developers] vtkOpenGLCamera ignoring vtkRenderer aspect.

[Moreland, Kenneth]

The vtkOpenGLCamera class is ignoring the aspect set in the vtkRenderer
given to it while setting the projection matrix in VTK 4.1 (or at least the
version I downloaded on June 27).  Starting at line 145 in
vtkOpenGLCamera.cxx, ComputeAspect and GetAspect are called on the renderer,
but then the aspect that is retrieved is ignored.  Instead, the perspective
seems to be decided by the viewport.

Is this a case of fixing something that wasn't broken?  In VTK 4.0, the
vtkOpenGLCamera class properly uses the aspect computed by the renderer, and
the ComputeAspect method does take the viewport into account.
