Needed because a group layer's projection can have a different type
than its image, at least at some pathologic moment during image type
conversion. But even if it didn't, it's cleaner this way anyway.
* app/core/gimpprojectable.[ch]: add the new vfunc plus public API.
* app/core/gimpprojection.c: use it instead of using the type of the
image returned by gimp_projectable_get_image(). The get_image()
function is now unused in the projection and only needs to stay
because the projection is also a GimpPickable.
* app/core/gimpgrouplayer.c: implement GimpProjectable::get_image_type().
The only purpose of this change is to avoid having the "update"
signal twice on GimpGroupLayer (from GimpDrawable and from
GimpProjectable). Switch back to normal g_signal_connect()
in the projection.
Add GimpProjectable::get_offset() and gimp_projectable_get_offset()
which returns the offset of the projectable in image coordinates, so
we can have projections that act as a viewport onto things that live
in image coordinates.

* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.

Abstract the legacy projection code away into a virtual function
of GimpDrawable:
* app/core/gimpdrawable.[ch]: add new virtual function
GimpDrawable::project_region() which projects an area of a
drawable onto a passed in PixelRegion.
* app/core/Makefile.am
* app/core/gimpchannel-project.[ch]
* app/core/gimplayer-project.[ch]: new files which implement it.
* app/core/gimpchannel.c
* app/core/gimplayer.c: hook it in.
* app/core/gimpprojection-construct.c: get rid all the projection
code moved to above new files and project all drawables in one
loop.
* app/core/gimpprojectable.[ch]: remove the legacy methods
get_colormap() and get_components(), they are not needed any
longer.
* app/core/gimpimage.c: changed accordingly.

This should remove any image or viewable dependency from the
projection (apart from the projectable's get_image() method, but
that one is not supposed to return the projection's model but
rather the image the projection is part of).
* app/core/gimpprojectable.[ch]: add vfunc get_size() which
completes the API needed for GEGL projection.
Add vfuncs get_layers(), get_channels(), get_components() and
get_colormap() which are needed for the legacy projection code.
* app/core/gimpimage.c: implement the new methods.
* app/core/gimpprojection.c
* app/core/gimpprojection-construct.c: use them and remove all
calls to image and viewable API.

* app/core/gimpprojectable.[ch]: add signal "structure-changed"
and API to emit it.
* app/core/gimpimage.c: emit it when the image emits
"mode-changed" and "size-changed".
* app/core/gimpprojection.c: connect to the new signal instead of
"mode-changed" and "size-changed" to get rid of one more image
dependency.

* app/core/gimpprojectable.[ch]: add vitrual function
invalidate_preview().
* app/core/gimpimage.c: implement it and redirect to
gimp_viewable_invalidate_preview().
* app/core/gimpprojection.c: call the new API instead of
gimp_viewable_invalidate_preview(). Some cleanup in the disabled
cow-projection code.

Unfinished first step to make the projection independent of
GimpImage, also one step closer to layer grouping.
* app/core/Makefile.am
* app/core/core-types.h
* app/core/gimpprojectable.[ch]: add new interface which abstracts
something that can have a projection attached to it. Has "update"
and "flush" signals and get_graph() and get_image()
vfuncs. get_image() is temporary until the hack is finishes.
* app/core/gimpimage.[ch]: implement GimpProjectableInterface,
remove "update" and "flush" signals and made get_graph() a private
implementation of the interface method. Moved interface method
implementations after virtual function implementations.
* app/core/gimpprojection.[ch]: change member "image" to
"projectable" and use the projectable API as often as
possible. Still some implicit dependencies on the projectable
being an image left but it's getting close.
* app/core/gimpprojection-construct.c: same here.
