Revecter - new ECMAScript framework for SVG

Today debuted ECMAScript framework, created to work with SVG documents on the Internet.
From their blog :

SVG is a powerful format that needs to be presented to the public. It has already been proven that svg has the potential ( habr ), and we aim to present it using the revecter framework

Meanwhile, this release is only a demonstration of the functionality of the framework framework, rather than direct execution, it shows its potential.
The framework provides inheritance using prototypes ( prototype-esque ), makes it easy to move objects and perform other basic tasks. In addition, it has a powerful animation class used for cross-browser animation, or formally non-existent things.
It's a shame that IE is not supported at the moment, but support is planned.
