API status of low-level PDF text rendering classes

Hello,

In my application, I needed greater control over the rendering of text 
than the standard high-level iText API allows. For example, I had to 
support several line spacing modes, text wrapping around an arbitrary 
shape, etc.

To this end, I've been using low-level text processing classes such as 
BidiLine, PdfLine and PdfChunk (and also, 
PdfDocument.writeLineToContent()). As some of the required methods were 
protected or package-private, I had to declare one of my paragraph 
rendering classes as part of the com.lowagie.text.pdf package (luckily, 
the iText jar is not sealed).

It works perfectly well, but one is always a bit reluctant to use 
non-public members, and I think the low-level iText API would benefit 
from the text processing tools being made public.
Do you think that could be done in a future release? This part of the 
code seems to be already quite mature and of API-grade quality, so it 
could be a simple matter of changing access permissions. Of course, this 
is not at all an urgent request, just a suggestion ;)

Best Regards,
Damien Drix
