d932e58217 tjTransform() was not working properly if r.w=0 or r.h=0

ba5ea5143e Tile generation did not work with TJXFORM_HFLIP, because the underlying transform code was using an in-place algorithm, which modified the source coefficients after the first tile was generated. Thus, create a new option which allows TurboJPEG to turn off the in-place horizontal flip if there are multiple transforms being performed from the same set of coefficients.

0a325197de Since lossless transforms have such a high fixed performance cost, implement a mechanism for performing more than one at a time on the same source image.
