plug-ins: Replace guchar PDB parameters with more appropriate types
Tested this for plug-in-alienmap2
and plug-in-maze
via the Python console, both of which use guchar
parameters. Also tested this for script-fu-circuit
, which internally uses plug-in-maze
(there was no need to adjust arguments there).
There is currently only one PDB procedure left using guchar
, which is plug-in-exchange
. If appropriate, the guchar
parameters there can be changed to integers with values limited to 0-255.
The problem with guchar
is that it is currently not supported as a GimpProcedureConfig
property, meaning that guchar
PDB parameters cannot be modified before running a PDB procedure. If it is desirable allow modifying guchar
via config, I have a commit ready and can create another merge request for that.
