In my app descriptor file I've got all icon sizes specified - from 16 to 128px in 32 bit PNGs. But the icon in the application window is displayed with resampling. Instead of original 16*16image it takes larger one and resamples down to 16*16 px. As a result, the icon looks wierd.
How could I make AIR use 16*16 px icon instead of the larger one?
