Enhancement committed in 9598c88c8fbb117019dffc1e88e526dbe1559daf

This works with -dTextAlphaBits and -dGraphicsAlphaBits as well as sending the parameters via putdeviceprops. It also works for depths other than 24 which the original patch did not, and uses the colour depth to limit the maximum number of bits.
