Zoom in/ out #10

Closed amitaibu closed 12 years ago

Thanks for glfx, it's a really nice library!

I wonder if zoom in/ out is/ can be a filter -- or should I manipulate the directly to get the zoom feature?

You should be able to perform zoom yourself using the matrixWarp() filter, although depending on your use case it may be better to just resize the canvas and allow the browser to do scrolling itself.
