New saturation and brightness options

Raw output option for smaller SVGs

Minor new feature allows rendering unencoded images. In the case of SVG this can be used to output smaller plain-text data URIs (the default base64 encoding adds 33%).

SVG Support!

Adds support for SVG output while preserving backwards compatibility. Existing usage should be unchanged. To generate SVGs, pass format: 'svg' in options.
