The main problem is that PNG images with alpha data are painted by
CompositeImageDescriptor with a solid background.  
Additionally, the CompositeImageDescriptor can use alpha channel data in PNG
images to blend overlays into the base image.  This allows for less obnoxious
icon decorators.

No - this was fixed by Silenio in 3.3
