This is meant to replace gimp_image_get_colormap() (see also #9477). We likely won't need a gimp_image_set_palette() because we can simply edit the image's colormap/palette with GimpPalette API now and it is directly updated. For instance, the following code changes the first entry in the image palette to red, immediately: ```python i = Gimp.list_images()[0] p = i.get_palette() c = Gimp.RGB() c.r = 1.0 p.entry_set_color(0, c) ``` For this to work fine, I added a new concept to GimpData, which is that they can be tied to a GimpImage (instead of a GFile). Image palettes are not considered internals, they are just tied to their image, therefore they can be edited by scripts/plug-ins. Additionally with this commit, editing an image's colormap from libgimp API also generates undo steps now.
