[Laszlo-dev] Loading Fonts dynamic (Flash-runtime)

[Henry Minsky]

Hmm, the library file produced by swfmill seems to just have put a
"importAssets" swf instruction at the end of it, which references the
library file itself (by it's URL).

I don't think I ever tried that when I was experimenting with the
importAssets tag in the LPS; I tried putting it in the main app, which did
sort of work but forced the library to get loaded at the same time as the
main app was being loaded.

I never thought to put the importAssets tag in the library, because I guess
I figured it would load the assets into the child movieclip, and they still
wouldn't be usable from the root movieclip. I'll play with this and see if I
can get dynamically loaded resources to be attachable to views in the main
app.
