It's not magic. LanguageEnvironment >> #fontDownloadUrls contains the url
Things that subvert the ability to trace the code statically are what I refer to as "magic".
In this case, the problem is completely opaque from the debugger (see original stack-trace from Bernhard at the top of this thread). You just see #installExternalFontOn:encoding:encodingName:textStyleName: at the top (bottom?) of the stack and no one sends it.
Now after three days I finally came across it in the SAR's preamble. But sheesh, I wonder why is it necessary to fork that? We should either not fork or at least tag it as <magic: 'called from from the SAR preamble'>.
