It is BGRA for little endian and ARGB for big endian.

Use a colourspace with "A" if your filter correctly 
deals with transparency, "0" if your filter does 
not output the same alpha information as the input 
has.
You can allow both if the filter copies transparency 
correctly but does not need it.
