Tilman Hausherr updated PDFBOX-4068:
------------------------------------
    Description: 
We have a PDAppearanceContentStream for appearances but nothing for XObject 
forms.

What we need should extend PDAbstractContentStream and should have a 
constructor like
{code:java}
public PDFormContentStream(PDFormXObject form) throws IOException
{code}
Alternatively, why not replace PDAppearanceContentStream? Its parameter is 
extended from PDFormXObject so we could just use the base class.

We need this both for 2.0 and 3.* - we have users who have a really hard time 
fiddling with low level operators instead of using the methods.

In 2.0 we could replace the parameter of PDPageContentStream that is currently 
PDAppearanceStream. This would be a non breaking change.
