[vtkusers] android examples openGL ES 2.0

[Francesco R]

Thanks Dr. Martin for you reply. I just recompiled the current master with
API 19 (the version of android installed on the device is 4.4) and I can
confirm that I have the same issues as in my first email. Do you think it
can be related to my particular GPU (ARM Mali 400 MP)? What GPU do you have
on your device? Thank you!
