theora dev - Jul 2002 - VP3/QT: A new kdxlqt_CodecVersion patch

The new 3.2.6.1 codecs work great with QuickTime 6 (thank you!), but there's
no way for an application to identify them.  And since the older 3.2.1.x and
3.2.2.x installers will actually *downgrade* the installed version of VP3, it
would be nice if an application could warn the user.

The attached patch increments kdxlqt_CodecVersion (and documents all the
Component Manager arcana involved).  This version can be retrieved using the
Component Manager.

I've also attached a HACKING.txt file which can go in Codecs/quicktime/. 
This file describes (for now) all the different version numbers I've found
in the VP3 QuickTime codecs, and how to increment them correctly.  Handy for
those of us who don't know our way around yet. :-)

Dan Miller--are these patches acceptable?  If you have time to build official
binaries before Aug 1, I can get them sent to a commercial Win32 testing house
which will be testing our applications and in a wide variety of sadistic
configurations.

Many, many thanks for all your help!

Cheers,
Eric

Here's all the different version numbers we've found in the VP3
QuickTime
codec.  All of these need to be incremented when making a release.

If you find more version numbers in the

Y\XY[HJKB\\HH\[[X\X\[HX\XH]ZX[YCB\X][[]\pecial format.  Applications which
      require a particular version of VP3 should query this on startup,
      because older On2 VP3 installers will *downgrade* the installed

I'll do my best to incorporate all reasonable changes by Aug 1 (but no
promises).

I thought I had found teh kdxlqt_CodecVersion flag -- that's annoying.
Too many copies of the same data floating around.
