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

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
