: Do u have any suggestion that we can do a bitmap bliting with each pixel
: has its alpha channel? I'm trying to do Alphablending and just wonder
: that can microwindows support it?
Currently, the alphablending blitters use a constant alpha channel. While
this is on my list, a quick hack would allow a variable alpha channel passed
along, rather than the constant alpha. Check out the drivers in
microwin/src/drivers/fblin{8,16,24,32}.c
