Summary0000379: Incorrect hidden surface removal after prop picking
DescriptionProblem description
-------------------
After picking in a scene with 3D and 2D actors the depth buffering
for hidden surface removal does not work anymore.

The problem occurs under following circumstances:
- The render scene contains a mix of vtkProp3D and vtkActor2D objects.
- Picking with vtkPropPicker.

See URL below for a tcl script that
demonstrates the problem. Start the script, rotate the cube and pick
somewhere in the render area by pressing the key 'p'. Now you can see
that the hidden parts of the cube have not been removed.

Solution
--------
In file vtkOpenGLFreeTypeTextMapper.cxx (Revision: 1.35,
2003/11/10 21:05:22) insert the following statement after
line 351:

    glDepthFunc(GL_LEQUAL);

 Sounds good to me, actually it seems we forgot to propagate the cleanup code, so it's definitely a bug.
Commiting to CVS.
