stb_image_resize: warning: comparison between signed and unsigned integer expressions

[jasonrohrer]

I noticed these warnings today when compiling with g++ on a very old (10.5) version of MacOS.

I haven't seen similar warnings on Linux or Windows, and I haven't looked into the details of where the warnings are coming from.

But I thought I should log it here, just for future reference.

We're very close to releasing a significantly revised version of stb_image_resize, so it may or may not have the same issues.
