Added args/props support to Gradient Texture story

[IRobot1]

I've figure out enough to run the story book documentation. This is a simple test for submitting my first pull request.

I noticed when trying to add a 3rd stop and color for gradient texture, I got the following error.

Is this worth fixing? Using the storybook, its not possible to add a new stop and color at the same time.

The stops needs be between: 0 -> 1. Think of percentage: [0, 50%, 100%]
