/* Old OpenGL 1.0 used the third parameter (known as internalFormat) as an
integer, which indicated the bytes per pixel (bpp). Later in OpenGL 1.1
they switched to constants, like GL_RGB8. GL_RGB8 means 8 bits for each
channel (R,G,B), so it's equal to RGB24. It should be safe to pass the
image_bytes to internalFormat with newer OpenGL versions.
Anyway, I'm leaving this so as it was, it doesn't hurt, as OpenGL 1.1 is
about 10 years old too. -- alex
