The other gegl_chant_double_ui values are pretty obvious. What does
value "1.5" do?

The "1.5" is the UI exponent you were asking for in Gaussian Blur, 1.0 is linear. If 1.5 is not enough, you 
may try 2.0 or larger. For the slider step problem, I don't know much about that sorry... I think the new UI values you 
suggest are good. So please, try some more by tweaking the exponent and you can commit directly to GEGL master those 
changes, if you want.

OK, that would explain why lowering that value to below 1 made the slider act strangely. I'll do some more experimenting and submit a patch. In the meantime, anyone have an idea of the largest GB and USM values they actually have used for image editing?
