-----------
Multithreaded EXR files loading
Use multithreaded loading of EXR files which is enabling by call of
setGlobalThreadCount function from OpenEXR library to set up number
of used threads to number of system threads which speeds up loading
high-resolution files on multi-core / multi-cpu systems and allows
to work with high-resolution sequences in clip editor and sequencer.
