[Ves] How to color polydata with Scalars in VES

[Bo Yu]

Thank you for your information, Casey, the color do appear, but it seems
that was colored "vertex by vertex", not as I expected: "cell by cell".
I am using bitbucket with my colleagures. I'll try to create a new repo in
github to let you see.
