Summary:                    Lines drawn in wrong color while dragging
Description: 
This has shown up in my own code, but here is an easy way to reproduce:
Run the standard VTK Widget testbed with this command line:
    WidgetsCxxTests.exe TestAngleWidget3D -I
The 2 lines of the angle and the arc between them should always be red. With
recent Nvidia drivers, one of the lines and the arc between them turn black
during the initial animation or when using the mouse to click and drag the cross
hairs at the end of the lines. Release the mouse and the lines return to red.
They should never be black. It seems that lines being actively changed (moved or
color changed) are drawn with the wrong color. Simple repaints when nothing is
changing draw correctly.

I would like to base a large amount of future drawing code on VTK, but this
issue could force changes to those plans.

This might be an Nvidia device driver bug. Nvidia GeForce drivers 285.62 and
earlier are ok (XP or Windows 7, on GTS450, GTX550Ti, GTX570). All later drivers
show the problem. This has been submitted to Nvidia, but it's unknown if they
will make any changes for it. (Reference Number 120523-000266)
