87a0396922 stb_image.h: 16 bit TGAs don't really have an alpha channel 
I claimed that if the most significant bit of a 16bit pixel is set,
it should be opaque (as is suggested by some sources on the internet),
but implemented the opposite.
If implemented "correctly", lots of 16bit TGAs become invisible.. so I
guess 16bit TGAs aren't really supposed to have an alpha-channel, or at
least most 16bit TGAs (despite having set an "alpha-bit" in the "image
descriptor byte") in the wild don't seem to work like that.

So just assume 16bit non-greyscale TGAs are always STBI_rgb without
an alpha channel.

d235049322 stb_image.h: Fix TGA colormap support 
* Calculate correct stb format (incl. proper 16bit support) also when
  using a colormap (palette)
* Create colormap with tga_comp, to correctly support 16bit RGB
  (instead of using tga_palette_bits/8 and just copying the data)
* For TGAs with colormap, the TGA bits per pixel field specifies the
  size of an index to the colormap - the "real" color depth
  of the image is saved in the color map specification's bits per pixel
  field. I think only 8 and 16bit indices make sense (16 should be
  supported, otherwise the colormap length could be u8 instead of u16),
  so I added support for both.
* Helper functions stbi__tga_get_comp() to calculate stb pixelformat and
  stbi__tga_read_rgb16() to read one 16bit pixel and convert it to
  24/32bit RGB(A) - for less duplicate code

57409c3d15 stb_image.h: Improve stbi__tga_info() and stbi__tga_test() 
* for paletted images, .._info()'s comp should be based on the palette's
  bits per pixel, not the images bits per pixel (which describes the
  size of an index into the palette and is also checked now)
* make sure the color (map) type and the image type fields of the header
  are consistent (=> if TGA color type is 1 for paletted, the TGA image
  type must be 1 or 9)
* .._test() does some more checks and uses stbi__get16le() instead of
  stbi__get16be() - TGA is little endian.
* .._test() now always rewinds (sometimes it used to do only return 0;
  without rewinding)
* remove "error check" at the beginning of stbi__tga_load(), because
  all that is already tested in stbi__tga_test()

7453e1bfa4 stb_image.h: Support 15/16bit per pixel RGB(A) TGAs 
stbi__tga_* assumed that 16bit TGAs were Grayscale + Alpha.
However, if the TGA imagetype is not one of the gray ones, it's 16Bit
RGB data, with 5 Bits per channel. If the TGA image descriptor field
has alpha bits (the 3 least significant ones) set, the pixel's most
significant bit is for alpha: 1 for opaque and 0 for translucent.
Furthermore people claim that TGAs can also pretend to have 15bpp,
which is the same as 16bpp but definitely without alpha.

So 15/16bpp TGAs are now decoded to STBI_rgb(_alpha).

26c98260b6 Fix warnings about "conversion to a greater size" that appear in VS2015 in x64 with /W4. 
The warning concerns the return value of stbi_err, which is an int, being converted to a pointer. In VS2015 it seems casting directly from a 32-bit int to a 64-bit pointer triggers this warning. Worked around by first converting to a 64-bit int (here size_t) and then to a pointer.

f224bc2cdb stb_image: Progressive AC decoding - fix ZRL code. 
The original AC decoding logic handled ZRL (runs of 16 zeros)
incorrectly.

The problem is that the original flow set r=16 and skipped the
final coeff write when s=0. This is not actually correct. The
problem is the intervening "refinement" bits.

With the original logic, even once we decrement r to 0, we keep
reading more refinement bits for subsequent coefficients until
we find the next currently-unsent AC in the current scan. That is,
it works as if it was trying to place 17 new AC values, and only
bails at the last minute from actually setting that 17th value.

This is wrong. Once we've found the 16th previously-unsent AC, we
need to stop reading refinement bits, otherwise we get out of sync
with the bit stream (which expects us to read a huffman code next).

The easiest fix is to just do what the JPEG standard implicitly
assumes anyway: treat ZRL as a run of 15 zeros followed by an
explicit magnitude-zero AC coeff. (That is, leave s=0 and actually
write s). So this is what this fix does.

a60912f145 Avoid GCC sign-compare warning. 
GCC 4.7 gave the warning "signed and unsigned type in conditional
expression" because the ternary operator mixes signed and unsigned
integers. Fixed by casting to unsigned inside the "if" branch instead
of casting the result of the entire conditional.

4b0c6f6634 stb_image: NEON and SSE2 SIMD detection fixes. 
This fixes two things. First, the logic to disable SSE2 on
GCC unless "-msse2" was not specific enough, and ended up
disabling SIMD support on NEON targets entirely. Shuffle
the detection logic around to make that bit x86-specific.

Second, 32-bit MinGW assumes 16-byte aligned stacks, but this is
not in the Windows ABI and hence DLLs and callbacks don't
necessarily provide it. This caused a crash.

This can be fixed by providing the right command-line option,
which we have no control over. As a compromise, disable the SSE2
path on MinGW unless a specific #define explained in the comments
is set. That way, we default to safe (never-crashing) behavior
unless the user explicitly signals they know what they're doing.

c6a3235995 stb_image: IDCT kernel func ptr in stbi__jpeg 
I want to support SSE2 kernels that auto-detect. If implemented
using globals, this would trigger thread race checkers if stb_image
was used in multiple threads. Just make the kernels be explicitly
per-stbi__jpeg to avoid this.

(This commit is the first step in replacing existing STBI_SIMD
functionality.)

518306517c stb_image: JPEG dequant in decode_block not IDCT. 
Inside decode_block, we're still sparse, and we can use that
sparsity pattern without doing extra work to discover it.
