Ok, I found my mistake: the first texture is at z index 0, so I changed:

    glOrtho(0., 1., 1., 0., 0., 10.)

to:

    glOrtho(0., 1., 1., 0., -10., 10.)

and it now works.

Is there a way to optimize this code? On my old computer (P4 / GeForce FX 
5200), it takes 100% of the CPU with only a 640x480 windows. If I resize it 
to 320x200, it does not take more than 5%...

My next step will be to update the textures as the pictures change; what is 
the best way to do this?
