swfparse.cpp

// SWF file parser.
//
// I uploaded this file *as is* while I was in the middle
// of debugging something (so its a bit of a mess) but still,
// it fixes most (all?) of the bugs in the original parser
// and includes quite a bit more functionality.
//
// It also uses the Zlib stuff in ParseDefineBitsLossless()
// so you can either comment that out or grab the Zlib source
// and link it in.
//
// Cheers, David.
//
// Change History:
//
// 99.07.12:    Uploaded first version (as is)
// 99.07.22:    Added code to parse Flash 4 ActionScripts,
//              and switches to dump image/sound/tag data
//              Thanks to Jason Schuchert!
// 99.07.28:    More flash 4 actionscript.  
//              Added GetUrl2 (thanks Olivier)
//              Fixed callFrame (there's no arguments to print)
//              Added WaitForFrameExpression
//              - Jason Schuchert
// 99.10.21:    Now parses streaming sound and MP3 headers
//              - David Michie
// 99.10.28:    Now parses DefineMorphShape and correctly
//              interprets FLOAT values with ActionPush
//              - David Michie
// 99.11.02:    Now parses DefineFont2 and DefineEditText
//              - David Michie
