Dear ROOT developers,

Is there a way to make TShape semi-transparent, so it would
look like as it is made of coloured glass or coloured fog?
I would like to see the objects inside the selected volume,
as well as the shapes, located behind it.
I imagine that this option is included in GL package, 
I do not need something fancy like different refractive
indexes of the materials, just simple event inside the volume.

Merry X-mas to all of you,
Cheers,					- Volodia.
