Detailed Description

Encapsulates OpenGL shaders.

A shader can be constructed using an AbstractStringSource. A shader can be attached to a program using Program::attach(). A Shader subclasses either ChangeListener and Changeable to react to changing shader sources and to propagate this change to ChangeListeners.
