Description
Even though the underlying TIFF format (as well as libtiff) support comments in the generated file (via TIFFTAG_IMAGEDESCRIPTION), the implementation of QTiffHandler::supportsOption() returns false for Description, resulting in any metadata added to the QImage via QImage::setText() to be lost when saving a QImage as TIFF.
To be consistent with other image formats properly supporting saving the metadata as long as the format supports it, TIFF images should save that data as well.
