[vtk-developers] Factory issue for new VBO and VertexArray painters

[David E DeMarle]

This warning comes from the new way (starting in 6.1) in which regression
tests get their data.

Move the regression test baseline image into:
C:/Dev/vtk-gerrit/VTK/Rendering/OpenGL/Testing/Data/Baseline/
TestVBOandVertexArray.png

Run cmake, that will replace the above file with:
C:/Dev/vtk-gerrit/VTK/Rendering/OpenGL/Testing/Data/Baseline/
TestVBOandVertexArray.png.md5
And move the original into the bowels of git for safe keeping.

Now when you push to gerrit the regression test image and the corresponding
source code get committed together.

See http://www.vtk.org/Wiki/VTK/Git/Develop/Data
for more details.
