Scenes : actual disk size ?

[Bre901]

As the size of the scenes has been growing since C2 has been released, I think it would be interesting to add the actual disk size in the scene description data.

Unless I missed something, one only can see the (compressed) size of individual files, and, as the compression ratio is highly variable from scene to scene (see below), it is not possible to estimate the actual disk size.

compressed / uncompressed sizes in GB (ratio) :
- SouthernNorway4 : 8.5 / 32.6 (3.83) [edit] extra digit added to avoid unwanted smiley
- Jura Mont-Blanc2 : 3.5 / 9.6 (2.7)
- Scotland3 : 10.1 / 20.8 (2)
- BigPyrenees3 : 10.1 GB / 15.1 (1.5)

Thanks in advance
