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
