F_VN_TransformIntoDisplayableImageExp2
Transform an image into a displayable image and set a custom timestamp that can afterwards be read via ITcVnImageTimestamps. The source image will be released and zeroed while existing destination images will be released and overwritten with the function result. If bAllowDeepCopy equals false, the source image must not be used anywhere else and the transformation is always very fast. Otherwise, if bAllowDeepCopy equals true, a deep copy of the source image might be created if required, which will result in a longer execution time. If you want to use ipSrcImage after this function call, use F_VN_CopyIntoDisplayableImage instead. (expert function)
