Detailed Description

This class allows to use the currently set viewport in the global opengl state!

It is not the intention of the OpenGLFramework to work on a global scope! Use this class with caution and seldom even if it is convenient! Your classes will develop difficult behavior and will not be transportable outside a well defined state context! Nevertheless it is usefull to use passive components for the integration of concepts from the OpenGLFramework into old software.
