We only free the texture image data if you have called pfFreeTexImage()
_before_ the texture was formatted for the GL. In this case, the image
pointer gets a pfUnrefDelete() after the texture is formatted and the
GL copy has been created. The texture image pointer will then be changed to NULL.
If this was not done and and a new texture
image is assigned, we simply pfUnref() the old texture image pointer before
replacing it with the new one.
