 ### Bubble Sketch
 
-To use the `RCommand` constant `UNIFORMLENGTH` in JRubyArt (and java constants in general with jruby) you would normally need to address it in the following way:- `Java::Generative::RCommand::UNIFORMLENGTH`. However in the geomerative gem we have done `package_include 'geomerative'` for you so you can get away with the short form `RCommand::UNIFORMLENGTH`, but you do need the `RCommand::` prefix. For processing constants the full form for the `CENTER` constant would be `Java::ProcessingCore::PConstants::CENTER` but because we hate typing we have made the processing constant `CENTER` available without the `PConstants::` prefix. If you have namespace difficulties you can always fall back on the full forms.

 To make processing methods available in the `FontAgent` class (`font_agent.rb`) we `include` the `Processing::Proxy` module that gives similar access to that of a java inner class as used in vanilla processing.
