A new month has started.
Time for a new filter to post here for the "invisible" GimpChat visitors/members.

Issabella and myself did conclude the tests of this wip which derives from the previous ones called JVID_EFFECT_L/LA (watercolor effect).

The new name came out from 2 facts:
- a comment by Erisian after the first tests of the WIP
- the many modifications done which suggest a new name and not just an update release of the base used

So, here the filter:

It has no prerequisites, except G'MIC, almost always present in Gimp installations.

Note: the filter does not accept source images with an excessive presence of black/very dark colours, like this PIXABAY image (the result would be ugly):

If you try, it will terminate the execution with an error message explaining the problem.
If you want to have it processed, you can previously change the black with a colour or a pattern not so dark.

Hints:

-Blur amount: applied as first step, if desired. It's a median blur.
-Sketch amount: gives a bit of relevance to some pieces of the image contours
-Posterize: it's a component of the process to flatten a bit the areas
-Chroma amount: as the word says, adds a bit of chroma
-Ageing amount: gives to the outcome a look of an old painting
-Frame amount: extend the minimum fuzzy frame always applied (% of the image)
-C2G amount: used to give one of 3 different final looks (if not 0) using the next parameter:
-C2G layer mode:
. -LUMINANCE=adds a light contrast
. -DODGE=creates a sort of a "sketch on white" (common for aquarels)
. -BURN=adding strength to the colours
-Sketch on top: reinforces the "sketch" look of the outcome
