Daniel Gibson 15516199e5 stb_image_write: Update JPEG code to jo_jpeg 1.60
For quality <= 90, it now supports subsampling U and V
so it encodes smaller files.

See https://www.jonolick.com/home/jo_jpeg-release-160 for more info
about jo_jpeg 1.60

Andrew Kensler 57b9ea6510 Quell -Wcast-align warnings from Clang
The stbi__sbraw() macro in stb_image_write.h causes Clang to spew about 24
warnings complaining that "cast from 'unsigned char *' to 'int *' increases
required alignment from 1 to 4" when compiled with the -Wcast-align option.

In practice, this is spurious so long as STBIW_MALLOC() and STBIW_REALLOC()
follow the usual alignment semantics for malloc() and realloc() in that they
align sufficiently for any built-in type.

To quell the warning, we can cast through a void pointer as an intermediary.

Daniel Gibson 1ad30e4e77 stb_image_write.h: Fix jpg flipping for non-multiple-of-8 sizes
JPG always encodes 8x8 pixel blocks. If the input image does not have
a width or height that's a multiple of 8, the last column or row is just
used multiple times for the remaining pixels of the block.
The original code first calculated p (the index into the pixel data)
with the "imaginary" row/colum (that might be up to 7 pixels too far
into each direction) and then subtracted the necessary amount of bytes
it if row >= height or col >= width.
That was a bit cryptic (IMHO), and didn't get more readable/obvious when
vertical flipping was added - which introduced a bug, by not taking
stbi__flip_vertically_on_write into account when adjusting p for
row >= height...

The code should be more obvious (and less buggy) now.

This fixes bug #592

Simon Rodriguez 34f087ce4c stb_image_write: fix indexing error when computing PNG filters with the stbi__flip_vertically_on_write on.
The PNG filters of the pixels row N are computed using row N-1 of the final image. If the image should be flipped when saving, this corresponds to row N+1 of the initial image.
