This is the only place where it is called. There was also no need for this function to be virtual since it's not reimplemented anywhere. This also fixes the GLTexturePrivate being created only to be immediately deleted and replaced by a new GLTexturePrivate when the GLTexture(QImage) constructor was used. With this change the structure of the GLTexture effectively becomes immutable to the outside world; the contents of the texture images can change, but the texture images themselves cannot be reallocated.
