openfl dev compatibility fixes
I tried out openfl-player and found some issues with runtime Swf parsing and swflite. these were the changes needed to get the project working.
I couldn't get any swfs to render on html5, except with swflite. the only swf that worked on html5 with swflite was badgerbadger, and my own custom swf. @barisyild mentioned they couldn't get as2 swfs to work with swflite. Any leads on why html5 doesn't work without swflite would be greatly appreciated.
I'm not sure this is the best way to handle, things. Specifically MovieClip.setChildField and SpriteSymbol.__setConstructor. The use of __constructor here seems odd and dangerous, to begin with. why not just call __constructor on the created movieclip in __createObject?
This isn't a real PR, it's used for swfs in Funkin, I do recommend applying similar fixes to swf, but that should be done by someone more familiar with the lib
