f502cae91a rename everything to do with premultiplied alpha since the whole
point is that this is for handling *non*-premultiplied alpha (since
correct handling of premultiplied alpha requires doing nothing)

ebc2d23d47 realized the 2 colorbytes case is impossible.
also updated the comment at the top of the file to reflect stbi_write_tga's new capabilities.

10def9b150 fix MSVC-ARM internal compiler error by wrapping malloc
For some reason Microsoft CL compiler for ARM is unable to compile malloc when parameter is an expression. malloc(x * y) will cause internal compiler error, malloc(x) is however fine.

260741ed33 vorbis warnings from ronny chevalier
I manually made these changes because they
disabled some substantial amounts of code,
and I wanted to make sure this wasn't due to
original code having bugs or deviating from
the specification

e05ebdbf1e My guess is people who care about premultiply also care about color space. 2014-07-31 19:37:42 -07:00

d75488b0e8 Do the multiply inline, it should be a tad faster and not corrupt our data. 2014-07-31 19:00:48 -07:00

ebe0473d8b Add a test suite to do a bunch of different resizes to find problems. One problem found was an incorrect calculation of texel support how many margin texels needed when downsampling. When downsampling we need to spread out the support of each contributing texel, so to compensate you need more margin texels. 2014-07-29 22:50:06 -07:00
