-----------------------------------------------------------------
[~lehmi] are we fine with taking that patch without an ICLA? IMHO it's small
enough.
[~mveron] thanks for the contribution. I'll apply it later tomorrow with some
minor changes.
- the {{AnnotationsFilter}} shouldn't be part of the
{{org.apache.pdfbox.filter}} package as this is related to io. I'll put it in
the {{.interactive.annotation}} package
- I'll add the setter/getter to {{PageDrawer}} too as the line {{for
(PDAnnotation annotation :
getPage().getAnnotations(getRenderer().getAnnotationsFilter()))}} introduces a
dependency on {{PageRenderer}}. Given the comment in the source code of
{{PageDrawer}} we might be removing the {{PageRenderer}} at some point in time
as a member in {{PageDrawer}}.
Again thank you very much for your help

> Regardless if annotations are supposed to be printed or not on the PDF, would
> it not be interesting to possess a flag allowing to choose if annotations
