some remarks on GCBuild16

[digitalis]

Hi,

Some minor things :
- I changed 'thin flows sediment ' to 'thin flows deep', but in the filter settings 'thin flows sediment (1)' remained visible as selection. Is this useful? I think not (no effect).
- filter 'thin flows deep (1)' removed, then added again 'thin flows deep (2); when I selected filter settings 'thin flows deep (2)' there was no filter effect visible, with 'thin flows deep (1)' it was OK. ???

A tip :
- when you first apply 'thin flows deep' , you can see where the rivers flow.
So when you then put 'springs' tabs at the beginning of the flows, you can predict where they will flow further (possibly in combination with the thin flows).

Regards.

The selections are not deleted if a filter was changed, because you can still use this selection, even if it is not used for generating. Well, you must once run a generation, so that a flowmap was generated.
The sense: Different erosions produce different flowmaps, and this behavior enables you to run an erosion only for getting the flowmap for shading or for use with an displacment.
