Extensions

Extensions are simply a way for custom code to be run after loading elements and skins. Simply place a .lua file in the extensions directory, and it will be required.

Standard Extensions

There is only one standard extension, which modifies element classes to add a more convenient getter/setter method to most get/set methods. For example, instead of element:getSize(), just call element:size(). Instead of element:setSize(w, h), call element:size(w, h).

This is mostly for a demo of what can be possible, but also might be useful.
