Multi-threaded frame calculation for movie clip proxies
This commit implements multi-threaded calculation of frames
when building proxies. Both scaling and undistortion steps
are now threaded.
Frames and proxy resolution are still handled one-by-one,
saving files after every single step. So if HDD is not so
fast, this commit could have not so much benefit.
Internal changes:
- Added IMB_scaleImBuf_threaded which scales given image
buffer in multiple threads and uses bilinear filtering.
- libmv's camera intrinsics now have SetThreads() method
which is used to specify how many OpenMP threads to use
for buffer distortion/undistortion.
And yeah, this code is using OpenMP for threading.
- Reshuffled a bit libmv-capi calls and added function
BKE_tracking_distortion_set_threads to specify number
of threads used by intrinscis.
