Update Sprite parameters in real time.

[mothervolcano]

Find a way to control Sprite parameters from the UI without requiring the re-instantiation of the Model.

Generating a new composition will be unavoidable and the change won't be smooth.

From a user point of view a regenerate button or mode will make sense.

It's important to make a distinction between the UI controls that:

A) Modify the drawing parameters: the changes are gradual (continuous) and smooth.

B) Modify the structure: the changes can be jumpy or flickery (discrete). They will also be computationally more expensive.
