WinCE Port: ARM version of PocketPCHalf
|Reported by:||SF/robinwatts||Owned by:||SF/knakos|
This patch offers an ARM assembly version of the PocketPCHalf scaler. This scaler is used for "The Curse of Monkey Island" to take a 640x480 screen (in either 565 or 555 format) down to 320x240 by averaging groups of 4 pixels together.
The ARM version is almost exactly the same as the C version, except it gets the rounding of pixel components correct.
