Updated GwtGL Roadmap

Much has changed in the last weeks:

• WebGL 1.0 is final! 
• Google Chrome 10 supports WebGL
• Firefox 4 (of course with WebGL support) is on its way
• A first preview of Opera with WebGL support was released

So we decided to update the GwtGL roadmap. We planned 3 releases:

• 0.3 will be released to support Chrome 10 and Firefox 4
• 0.9 will provide support for the GWT 2.2 Canvas widget together with a renewal of the WebGlRenderingContext.
• 1.0 will be our first stable release

Sadly GwtGL 0.9 will break some of the existing APIs.
