	* OpenImageIO: deactivation of several image formats that seem unrelated to or unsupported by LuxCore: freetype, hdf5, ffmpeg, libheif, ptex, opencv~~, webp~~. This removal spares both compilation time and build result size. Those formats are reactivable, in case they were missing.		* OpenImageIO: deactivation of several image formats that seem unrelated to or unsupported by LuxCore: freetype, hdf5, ffmpeg, libheif, ptex, opencv.
