742110ccce Speed up ApplyPalette for ARGB pixels. 
Added 1 pixel cache for palette colors for faster lookup.
This will speedup images that require ApplyPalette by 6.5% for lossless
compression.

James Zern
d8edd83551 libwebp: fix vp8 encoder mem alloc offsetting 
'mem' was being offset once by DO_ALIGN() then shifted 'nz_size' which
would end up accounting for more than ALIGN_CST and exceed the allocation.

broken since:
  9bf3129 align VP8Encoder::nz_ allocation

64c844863a Further reduce memory to decode lossy+alpha images 
Earlier such images were using roughly 9 * width * height bytes for
decoding. Now, they take 6 * width * height memory.
