3D column - disabled animation

[pawelfus]

When animation is disabled, zIndex's are wrong, demo: http://jsfiddle.net/07ja16qg/

Workaround:

Instead of disabling animation, set the duration to 1: http://jsfiddle.net/07ja16qg/1/

Additional issue, even with enabled animation: http://jsfiddle.net/8rn3cs8q/1/

Drag the chart around, eventually we will get the issue:

In short:

• indexes are not updated after initial rendering in the redraw() function
• current zIndex is miscalculated (uses top shape of the cuboid, while should use bottom one - it works with animation because.. height=1 so top shape and bottom shape are almost at the same place).
