98d0d19208 lagarith: pad RGB buffer by 1 byte. 
For left HFYU prediction, we predict from the buffer buf+1 using 8- or
16-byte reads. This means that aligning the buffer by 16 bytes is in
itself not sufficient, because if the width itself is 16- or 8-byte
aligned, the buffer will not be padded, and thus a read of size 16 at
buf+1 will overflow boundaries at the right edge. Padding the buffer by
1 byte is sufficient to not overflow its boundaries.

Fixes bug 342.

464e9ab011 lagarith: add YUY2 decoding support 
Unlike other variants, for YUY2 we need to use different prediction:
* on line 0 for luma we should left predict starting from the second pixel
* on line 1 we should left predict first 4 pixels for luma and 2 for chroma
* median prediction employed here is taken directly from HuffYUV

It's more readable and less prone to breakage.

b0c8b8a69d Lagarith: fix decoding of one-coloured frames by reading the per-plane 
color value instead of always taking 0 (resulting in green frames).
