Benny Siegert	14c59abd76	image/tiff: Reject images with SampleFormat != 1. ... The TIFF spec says that a baseline TIFF reader must gracefully terminate when the image has a SampleFormat tag which it does not support. For baseline compatibility, only SampleFormat=1 (the default) is needed. Images with other sample formats (e.g. floating-point color values) are very rare in practice.

Benny Siegert	d97b8a817b	image/tiff: implement a decoder. ... The current iteration can decode 8-bit images in grayscale, paletted, RGB, RGBA and NRGBA mode. LZW compression is implemented but does not work on my test images. Deflate (i.e. zlib) compression with or without a horizontal predictor is supported.
