I have warnings as errors enabled in Visual Studio, and I'm getting a few type conversion errors, "int -> stbi_uc", in the function "stbi__tga_read_rgb16".

I'm not confident enough to submit a pull request for this, but it would be nice if someone with proper knowledge of the library could fix the warnings (or tell me my compiler is stupid and I should just ignore them).
