The tool now takes care of the portion of the layer effectively displayed
on the screen. This allows faster expansion/shrink of the selection since
an area smaller than the whole layer is used.
It will also limit the impact of the incoming multilevels processing, which
tends to decrease the segmentation accuracy on thin structures, since users
often zoom-in to work on such thin details.
A -quick done- first step towards the addition of a smart selection tool.
Require the gegl:paint-select workshop operation.
Still LOT of work to do (wip):
- fluctuations removal (GEGL side)
- multilevels pyramid approach + banded graphcut for instant result on large
image (GEGL ? GIMP ?)
- Gaussian Mixtures for color models (GEGL side)
- drawable offsets (GIMP side)
- undo / redo (GIMP side)
- scribbles edition mode (GIMP side)
- dedicated icons
- ...
