To avoid stupid limits let's > allocate 32bit int for value that is silly. 8bits (0-255) is really all you need. any more is sheer overkill. personally i'd allow for deeper pixmap masks - but i woudlnt impliment support for them simply because its a massive waste of memory, bandwidth etc. for no gain. no decently available hardware supports more than 8bits for alpha value - and implmenting an optminised software alpha blender for > 8bits is a pain and basically will be pretty slow. dont make apps have to provide 32bits for alpha. thats a LOt of data to generate and pump over to the server.. that then has to munge it down. not to mention 8bits fits much nicer in packign it in with rgb triplets. > of alpha channel of one pixel.
