Diego Elio Pettenò	2597a842a0	tiff: Improve grayscale support Only use PAL8 if palette is present, else use GRAY8 for pixfmt.

Hendrik Leppkes	edcc51fb8e	tiff: fix handling of metadata with refcounted frames Since the conversion to refcounted frames, the tiff decoder only wrote the metadata into its internal "picture" in its own context, never exposing the metadata to the user, and eventually leaking the metadata. Instead, properly store the metadata directly into the frame being decoded into. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
