Fix the dependency by making the stamp an actual (yet empty/no-op)
header file which is included by all generated source file. This way, we
ensure that meson rebuild .o files when the .pdb sources are changed.
This is the second solution proposed by eli-schwartz here:
https://github.com/mesonbuild/meson/issues/10196#issuecomment-1080053413
Turn all ID param specs into object param specs (e.g. GimpParamImageID
becomes GimpParamImage) and convert between IDs and objects in
gimpgpparams.c directly above the the wire protocol, so all of app/,
libgimp/ and plug-ins/ can deal directly with objects down to the
lowest level and not care about IDs.
Use the actual object param specs for procedure arguments and return
values again instead of a plain g_param_spec_object() and bring back
the none_ok parameter.
This implies changing the PDB type checking functions to work on pure
integers instead of IDs (one can't check whether object creation is
possible if performing that check requires the object to already
exist).
For example gimp_foo_is_valid() becomes gimp_foo_id_is_valid() and is
not involved in automatic object creation magic at the protocol
level. Added wrappers which still say gimp_foo_is_valid() and take the
respective objects.
Adapted all code, and it all becomes nicer and less convoluted, even
the generated PDB wrappers in app/ and libgimp/.
on behalf of plug-in authors who have no style or can't type.
Instead, simply reject non-canonical procedure names and remove all
code that keeps aroud the original non-canonical shit just to pass it
back to the plug-in.
Instead just transform the measurement extremities appropriately to
still map to the same points.
To do so, I also added out parameters to gimp_image_resize_to_layers()
so that calling code can get offsets from old origin (as well as new
image dimensions).
Add a GimpFillType argument to GimpItem::resize() and fill type
widgets to the canvas and layer resize dialogs. Fill the new parts of
the drawable according to fill type in gimp_drawable_resize(). Make
sure places that need the old behavior get GIMP_FILL_TRANSPARENT
passed by hardcoding it in the GimpItem::resize() implemetations of
channel, mask, selection etc.
