removed stray temporary file
LICE: added LICE_BitmapCmpEx() for comparing ignoring bitmask -- from 97ae08bd
lice_gif_write: allow writing less than 256 colors to file when not needed -- from 4f4fe41a
LICE_palette: LICE_BuildOctreeForAlpha/Diff return pixel-diff count rather than leaf count
lice_gif_write: avoid generating a 32kb lookup table when the number of pixels being generated is less than 40,000
LICE_gif_write: fixed transparency for partial updates, oops -- from e3256229
LICE_gif_write: improved auto-transparency logic -- from 921418d8
lice_gif_write: properly support variable alpha threshold for caller-alpha, also support mask in auto-transparency mode by using low 8 bits of transalpha as mask -- from 95749e6d
lice_gif_write: if transalpha has 0x100 cleared, don't use fancy new statistics to decide whether or not to use transparency -- from a912e96f
Merge remote-tracking branch 'wdl-public/master'
LICEcap: use mask for low bits of pixels (5 bits of precision is enough for licecap gifs)

LICEcap: multiple .gif writing test for comparing different encoder settings -- from 55fef176, 1ee61631
