[Emmanuel Saint-loubert-Bié, 2012/08/03 14:28:26]

I had forgotten the exact scheme when we discussed all of this. So I think the
gradients will look a lot better if we have 2 kinds too, 800 tall and 1700 tall.
I can provide the assets later on. 
If you do this then please introduce new IDs (and in the grd you can point to
the same files for now.)

[bshe, 2012/08/03 15:01:33]

Added new IDS. Will add folder to the gradient images after you landed the
assets.
