Hi Aurelien,
thanks for the hints. I was also suggested by someone else to either
subclass or do what you have done, but I found it working with this
Texture::TextureObject trick, and it works well, so I am not to leave this
method only was curious if there is something else to be set to get rid of
the warning. Thanks again
Nick
