Don't worry about that -- I was just thinking out loud about things we could do 
:)

I do like that notation style ;)  Apart from that I for sure have not used it 
on Windows;  don't worry about that either and thanks for double-checking! :)

As you are now moving into the implementation phase of your project I would 
quickly like to recall my message from about a month ago:  
https://lists.nongnu.org/archive/html/freetype-devel/2020-05/msg00165.html.  
Don't worry about exact naming and we might need more functions and/or more 
arguments but outlining the general idea:  I would very much appreciate it if 
we could find a way to wrap FT logging into a public interface that works 
something along these lines.  So basically there's a default log callback 
implemented internally that listens to environment variables (and/or other, 
more dynamic inputs) and then there's a way to overwrite this callback from the 
outside by providing (a) custom function(s).  All details are obviously up for 
discussion :)
