Replace PDFSharp to improve cross platform compatability

I'm wondering if it might be possible to somehow use MAUI and its skia backed canvas to replace PDFSharp? The main loss would probably be easy PDF export and printing might be more difficult to accomplish but it would give the whole project a much better cross-platform story. This would pair pretty nicely with the goal of converting the code to dotnet 6 as well. Lots of effort though.

I'm looking at a few different options, including MAUI as options. None are going to be a small effort, but I think it will be worth it in the end.

PDF support I will try and separate from the drawing engine (as it looks like I'll have no choice really), but that should give me more options in both aspects.
