are there any plans to support straight alpha channel information as the PNG
format requires or will pov-ray remain in partial complience with the PNG
standard?  is there any known way to enable this functionality in v3.1 or
v3.5?

we are trying to render objects with transparency and composite them in a
game using the alpha channel, but the current output produces inadequate
results; the object displays fringes of the render background color.
