e4d38d1d3e clip out of bounds GIF images against the canvas 
Some malformed GIFs have images which lie outside or partly outside the canvas.
With this patch, these frames are clipped and rendered.

Previously, these GIFs were rejected.

41961f138a webpsave: when minimising the size of an animated WebP image, 
allow the encoder to evaluate and mix lossy+lossless frames,
which minimises the size of the file by a further ~5%.

9246094033 Fix function pointer cast issues 
It is undefined behavior in C and C++ to cast a function pointer
to another type and call it that way. This does work in most native
platforms, however, despite it being UB, but in WASM it can fail.

See:

e129dfc27a fix TIFFReadScanline() call 
We were passing in 0 instead of -1, which could trigger an assert in
libtiff with some logluv images.

Also, fix logluv decode. We were not always resetting the decode format.
