OpenGL and transparency

We have an Android application which uses transparent stage for one of it’s basic features. We were able to accomplish that by tweaking file “openglcontext.cpp” and forcing it to use transparent color for opengl surface.
But in newer versions of OpenFL, there is no file openglcontext.cpp.

Could some1 give me pointers, how this could be achieved in the newer versions of OpenFL?

It appears that there is code that is meant to support a transparent stage. Could you try:

<window background="" />


<window background="0x00000000" />

and see?
