The scale of PDF items was sometimes badly calculated when opening a
document made with a previous version of OpenBoard or made on another
computer.
Specifically, this solves the following issues:
- PDF scale calculation in documents that did not specify the pageDPI
used to render the PDF (happened with documents created with some old
versions of OpenBoard)
- PDF scale calculation in multi-page documents (it was set correctly
for the first page, but not the following ones)
In some cases, the PDF background of a document could be scaled badly
when tools such as the ruler, compass etc. were present on the page.
This happened with PDFs of version <= 1.4, and when the tools were
outside of / larger than the page.
This fixes an issue where if one document was imported with a different
DPI than the current one, any document created thereafter would have
this same value (which could then cause problems if a PDF was added to
that new document).
Saving this value to UBDocumentProxy not only makes more sense, it also
fixes this issue.
