Earlier, at line#275, if ok == 0, it would have triggered a double free
of 'rgb'.

new option: -blend_alpha 0xrrggbb
also: don't force picture.use_argb value for lossless. Instead,
delay the YUVA<->ARGB conversion till WebPEncode() is called.
This make the blending more accurate when source is ARGB
and lossy compression is used (YUVA).
This has an effect on cropping/rescaling. E.g. for PNG, these
are now done in ARGB colorspace instead of YUV when lossy compression
is used.

(cherry picked from commit e7d9548c9b)
Tuned the cross_color transform parameter (step) for lower quality
levels. This change gives speedup of 20% at lower qualities (25) and 10% at
moderate quality level (50) with a loss of 0.25% in compression density.
Also removed TODO for cross_color transform. Observed good correlation of
this with the predict transform.

add a check for a libGL function (glOrtho) in addition to glutMainLoop
when establishing the need for libGL at link time.

This wasn't used often and benefits were likely minimal. Dropping it
outright is a bit simpler than adding a compatibility ifdef.
provides some compatibility with older versions of autoconf.

reuse the declarations from arrays_java.i for signed char to make an
explicit uint8_t mapping. this avoids sign conversion build warnings.

The auto-infer logic of detecting the 'Alpha' use case
(via check '(palette[i] & 0x00ff00ffu) != 0' is failing
for this corner case image with all black pixels (rgb = 0)
and different Alpha values.

Added 1 pixel cache for palette colors for faster lookup.
This will speedup images that require ApplyPalette by 6.5% for lossless
compression.

'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.
