This means that if you have WITH_BF_QUICKTIME or WITH_CODEC_QUICKTIME enabled,
it will always use QTKit.
The old backend was only used on 32 bit OS X builds, now 32 and 64 bit builds will
give consistent input/output. On Windows or Linux quicktime isn't being used.
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
Supports default OSX codecs : Linear PCM, Apple Lossless and AAC
Note that AAC codec doesn't support sample rates above 48kHz. If a python/rna guru knows how to easily enforce this limit, he is welcome!
Enjoy making Quicktime movies now with audio!
This makes quicktime import (.mov & quicktime handled image files such as .gif) available also for 64bit OSX
Unfortunately, Apple currently incomplete implementation of QTKit has much lower performance than old Carbon Quicktime.
FYI, it spawns a 32bit process "QTKitserver" to place calls to Quicktime 7.
So this is mostly meant as a "backup" for 64bit OSX builds, until Apple releases full Quicktime X.
Export part will come just after.
CMake scripts updated: set WITH_QUICKTIME and USE_QTKIT to ON
