If I render an object, and the edge of that object only covers half of a pixel, why does it need more than half the colour range?

OK then, if I bow to the prevailing wisdom, what it boils down to is that I could load an image file containing pre-multiplied alpha without being asked if the alpha should be un-multiplied. (Although I still think there's a useful distinction between pre-mult alpha and non-mult masks, and I would like to load an rgba image into Gimp and then add a mask layer.) A quick glance at the targa file spec reveals nothing about the intended meaning of the rgba data. -- David Hodson -- hodsond@xxxxxxx -- this night wounds time
