Summary:                    MakeCurrent() error with vtkPanel using the Java
wrappers under windows.
Description: 
Somtimes, when disposing a vtkPanel an error occurs in
vtkWin32OpenGLRenderWindow::MakeCurrent().

(Typically a vtkOutputWindow pops up, and the application crashes out)

Code that reliable reproduces the error is here:
https://github.com/lukedodd/lwjgl-vtkcanvas/blob/lwjgl-vtkcanvas/lwjglvtkcanvas/VTKMakeCurrentBugReproduce.java

In the context of a larger project I've had this error happen fairly
non-deterministically. I've had someone else report that the test case crashes
for them too.

This error happens under fairly similar circumstances to:
http://www.vtk.org/Bug/view.php?id=12756

But the panel must have it's Delete method called prior to disposing, which
judging from the source of vtkPanel is the only way to ensure memory is cleaned
up.

As with bug 0012756 my alternative vtkPanel class which is based on LWJGL fixes
the issue.

I've attached a stack trace of the MakeCurrent error.
