TXInitTextension changes current port?

TXNInitTextension changes the current port without being documented as doing so:

GetPort(&before);
OSStatus error = TXNInitTextension(&defaults, 1, kTXNWantMoviesMask | kTXNWantSoundMask | kTXNWantGraphicsMask);
GetPort(&after);
check_string(before == after, "TXNInitTextension changed the current port");

It'll assert.

I'm not sure that APIs should be implicitly changing the port on developers. Not sure if this is a bug in MLTE or an oversight in the documentation. I'd say a bug in MLTE.

I've reported this as bug 3259049 for what it's worth.
