/**
* An implementation helping to create a PDF content stream using higher level
* abstractions than the PDF operators.
*
* This object deals with two abstractions:
*
* The {@link CSContent}, a sequence of PDF operators. The {@link CSContent} can
* be read from an existing object like a {@link PDPage} or a {@link PDForm} or
* can be newly created, using the factory methods in {@link CSContent}.
*
* The second abstraction is the {@link IResourcesProvider} for the
* {@link PDResources} like Fonts, XObjects, ... that are referenced in the
* {@link CSContent}. The resources of the provider are not accessed until a
* resource relevant operation is created.
*
*
* This implementation is (nearly, see AffineTransform) independent of AWT or
* any other window toolkit.
