Rough Prototype

This release represents the first solid proof of concept of SpriteMaker.

Users can create Rectangles, Circles, Rounded Rectangles and Fills. These Draw Commands are a first pass and may be rough in extreme cases. Much of the anti-aliasing solutions in the Draw Commands are incorrect and will be changed in the future.

Developers can create their own Draw Commands by subclassing BaseDrawCommand.cs. DrawToColorArray() performs the actual drawing, while DrawControls() allows the developer to expose custom variables to the User.
