Calling gimp_selection_float from a Python plug-in could make it crash
with an error like Calling error for procedure 'gimp-selection-float':
Item x cannot be used because it is not a group item.
This is caused by an incorrect check for group layers.
gimp_pdb_item_is_group returns an error when the condition is False,
while we only want an error when a group layer is selected (True).
Thus we need to use gimp_pdb_item_is_not_group, which returns an error
when the item is a group, which is what we want.
These function names are a little confusing, we might need to think
about better naming sometime.
I added C/Python tests for this function, so that we can test whether
this works correctly.
This fixes bugs introduced in commit a7c59277fb where I obviously didn't
properly checked all the places where gimp_selection_float() was used
after its parameters changed.
Add a "gboolean edge_lock" parameter to GimpChannel::feather() and a
"Selected areas continue outside the image" toggle to the "Feather
Selection" dialog, just like they exist for shrink selection and
border selection. At the end, convert the boolean to the right abyss
policy for gegl:gaussian-blur.
Make sure a channel -> selection -> channel roundtrip never does any
gamma conversion.
In gimp_channel_duplicate(), make sure a created channel has the
right format, and the right data. Fixes selection -> channel.
When switching off quick mask, call gimp_item_to_selection() instead
if gimp_selection_load(), the latter was implementing a shortcut which
is now wrong.
Remove gimp_selection_load() which is now unused.
Unrelated: also remove gimp_selection_save(), it was an obvious
3-liner used only twice.
It never belonged inside "tools". Also rename its "pdb" subdirectory
to "groups". This had to happen before 2.10 so cherry-picking between
branches doesn't become a nightmare in the future.
