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

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.

Removed broken wrap from fractals
Used varied seeds for fractal octaves to remove artifact at origin
Removed indicies table in favour of mod12 permutation table, this reduces gradient bias and gives 3% performance increase
