There are two commits to fix this:


I simply didn't have enough time to test these. They compile and "work
for me". But this eventually breaks embedded font handling and some code
I changed didn't made much sense. There were some reinterpret_cast stuff
to fit those embedded font handling into the normal font handling in
some obscure way, I don't yet grok. Then there is the hb_font handling
on Windows, which - I guess for some resource handling - is places in
the PhysicalFontFace instead of the LogicalFontInstance.

But currently I don't have time to test this with all the stuff (AKA a
Windows and Mac build, embedded font handling).

Probably it would be easier to just move the Qt5 stuff; but then I
wanted to clean this up and move the platform specific code into their
respective VCL modules. I also started writing documentation, about the
way the font handling works / should work.

Fact is I'm currently overwhelmed by non-LO work. If someone else has
some time do the testing I would be happy. I can push this, but don't
have time to fix regressions.

And I would like to mentor some Qt5 GSoC, which I have to replace the
KDE stuff on the ideas page.

And I have rebased patches, if that helps.
