Visualization: DSL to scale the Image

[da-liii]

## Scale the image
image = Image("path/to/xyz.jpg")

image1 = image * 2
image2 = image * 0.5
image3 = image * (1, 2)
image4 = image * (2, 1)
image5 = image * (1, 0.5)
image6 = image * (0.5, 1)

## Scale the image and then append the RelativeBox2d
(image * (x, y)) | RelativeBox2d(0.a, 0.b)

Hmmm does this mean we add a Transform abstraction to Rikai.viz? Then you can scale/translate/add noise etc ? Wdyt @eddyxu

I can see how resize work. How does general transform work , in what context?

image * (1, 2) deserves a PR for sure.
