In gimp_group_layer_update_size(), when the new size happens to be the
same as the old size, we need to call gimp_pickable_flush() on the
group projection so it is ready to be used for rendering the image,
just like in gimp_group_layer_stack_update().
and pass them where we know the buffer could be from another image.
Pass "NULL, 0" if we know it's the same image.
Add gimp_layer_new_convert_profile() which takes the newly created
layer and the ICC data/length; call it from both
gimp_layer_new_from_gegl_buffer() and gimp_layer_new_from_pixbuf().
gimp_layer_new_convert_profile() is empty, this is just
infrastructure.
Set the profile when the buffer is copied from a layer, and when it's
created from a GdkPixbuf from the clipboard. The profile is not yet
used for anything.
Add Image -> Color Management -> Discard Color Profile which simply
removes the profile without any conversion.
Also added actions and callbacks for "Assign" and "Convert" but these
are only stubs to be filled as replacement for the remaining code in
the lcms plug-in.
and move the color profile menu entries there. Add a mapping so 3rd
party plug-ins get moved to the new location automatically.
Also, add a separator after "Duplicate" and move the "Transform"
submenu to the top of the group that has "Scale", "Resize" etc.
...when opened by the "Edit these settings as Curves" button on the
Levels dialog
The code to configure the entire GUI correctly was not even called
when initially creating the curves dialog (the color bars probably
looked right just because of default values of their own).
Factor out gimp_curves_tool_update_channel() which properly updates
the GUI. Call it after the dialog has been created, and when the
active channel changes.
Implement GimpConfigInterface::duplicate() and after duplicating the
paint options, copy the brush-related properties again, because they
might have been changed by setting the brush on the copy (if they are
set to be linked to the brush's native values).
For instance, modifying a layer and going directly to draw in the canvas
should not cancel the layer name.
You can still cancel a layer renaming in progress with ESC.
but they aren't clipped
Add gimp_display_shell_profile_can_convert_to_u8() which returns
whether the lcms transform can safely write directly into an u8 buffer
without destroying out-of-gammut pixel values, which we assume is the
case for all integer formats. If the function returns FALSE, always
convert via the R'G'B'A float filter_buffer.
Also connect to the image's "precision-changed" signal and update the
profile transform when it's emitted.
