What's the story behind this? Observe thou the humble salix
babylonica, fore a striped backgroun and three media-containing
cylinders. The cylinder on the left is filled with absorbing,
the middle with emitting, and the right with scattering media.
The alpha-channel-containing textures that represent the leaves
behave most oddly when there is absorbing or scattering media
behind them.

Let me just say that perhaps when trying to show that
something behaves odd, you shouldn't use white as a
color, when white is what you get as a side-effect...
Aside of that, try putting hollow onto the leaves.

Um you can see the same effect behind the grey and green
stripes too; it's why I put them there.

Its a well-known issue which 2D objects like triangles and disc,
but its not documented. I've no clue whats causing this, but
whenever I spot problem with media, I look for objects obscuring
the media, and if they are 2D and don't have hollow.

Would be nice if it were documented.
