Might be unneeded complexity. For a selection outline preview, it
would be simpler to apply the magic wand to a shrunk version of the
image while it is in operation, and only apply the magic wand to the
complete image when the user releases the button.

This would require channels to be drawn after the gray->RGB internal
conversion but before the display filters come into effect.

This might be tricky, but doable. I would find it very useful. To be
this probably would need to just draw an extruded diamond (the points
of the diamond
being the midpoints of each side of the brush image.

Cairo might help here.

beyond 2.6, but definitely something desirable in the long term -- one

nice simple enhancement.

.. It would then not be automatic white balance, but manual or
partially-automatic white balance.

Is this really related to dodge/burn tool?
Isn't a curves brush a case of 'filter brush'?

Could you present evidence of this? From what I understand of the
'auto levels' function, it can never reduce the range of the output,
only expand it, so any lack of detail is due to hidden lack of detail
in the input image.
