Sean Barrett 22fa9a467a rewrite HDR rle logic 2015-01-18 10:43:42 -08:00
Sean Barrett 5b53d20c68 Put progressive JPEG AC decode logic back the way I wrote it originally (I changed it to match jpgd when I was trying to figure out why it didn't work); 
add STBI__ prefixes to internal SCAN_ enum;
strip unused function arguments for progressive funcs;
tweak release notes;
forget to git commit frequently so these would all be in their own commits;

Sean Barrett f5dfba0b8b Update stb_image test code to test loading with all channel counts (including 0),

*results*, but tests that it doesn't crash or fail.
