// Note: image loaders usually think of top left as being (0,0) while in OpenGL I would rather think of bottom left as being (0,0) as OpenGL does that already, so that is why I set the stb library to flip image vertically. There are other workarounds like flipping our texCoords upside down or flipping things in the vs or fs, but that would mean that we are choosing in OpenGL to work with two different coordinate systems, one upside-down from the other. I would rather choose not to do that and simply flip images when loading in. It is a matter of personal choice.
