Description

We have a PDAppearanceContentStream for appearances but nothing for XObject forms and tiling patterns.

What we need should extend PDAbstractContentStream and should have a constructor like

public PDFormContentStream(PDFormXObject form) throws IOException

Alternatively, why not replace PDAppearanceContentStream ? Its parameter PDAppearanceStream 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.
