When to use Processing::Proxy

Just in case it has passed you by, processing uses java inner classes to give your own classes access to the PApplet methods/variables. For ruby-processing you can include the Processing::Proxy module to give you a similar level of access, note the width and height variables are not available (you can use $app.width and $app.height to get round that). This all very non OO so you should use it only when you need it:-

Using refined includes in ruby-processing, don't over pollute your classes: http://t.co/WQ9OmnvgcV
