What is the point of doing them ? if re->mask is 0 (no destination mask target is given) BUT re->destination_alpha is 1 then we still want the destination buffer to have an alpha channel - this allows evas to render to argb windows and literally produce alpha channels xcomposite can use with compositing. > Vincent > > > ------------------------------------------------------- > This SF.Net email is sponsored by xPML, a groundbreaking scripting language > that extends applications into web and mobile media.
