  com.tensegrity.graphics.GraphicConfiguration

public final class GraphicConfiguration

extends java.lang.Object

The GraphicConfiguration class holds the information that configurates the graphic environment of the graphics API.
NOTICE:Currently this information is stored globally (means the graphic environment is actually configurable within the scope of a java runtime environment) but this will be changed in a former release of the graphics API such that this information is stored application wide.
