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().
When the projectable's size or image type changes, stop the idle
renderer and remove all queued update area because everything needs to
be re-rendered anyway. Also honor the projectable's offset when
invalidating the entire projection after clearing the pyramid.
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/Subtract the projectable's offset whenever we go from coordinates
from our public interface (which are always image coordinates) and
coordinates in out internal tile pyramid (wihch always starts at 0,0).
The Gegl projection still needs an offset node that is missing.
Also, connect to the projectable's "update" signal using
g_signal_connect_closure_by_id() instead of simply g_signal_connect(),
so we really connect to the signal of the GimpProjectable interface
and not to the "update" signal of GimpDrawable (which is a conflict
that will happen on group layers).
(gimp_projection_validate_tile): fix stupid braino that made the
recently added optimization loop infinitely on images with a width
that is a multiple of TILE_WIDTH.

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.

"projectable" and use the projectable API as often as

Speed up our display rendering code paths by keeping data with
pre-multiplied alpha where possible. The projection tile-manager

non-pre-multiplied pixel data.
* app/core/gimpprojection.[ch]: removed
gimp_projection_get_opacity(), the projection is always opaque.
* app/base/tile-pyramid.[ch]: use pre-multiplied alpha for the
upper levels of the pyramid. This speeds up validation of the
upper levels significantly.

the large lookup tables from gimprender.[ch] any longer.

Implemented an image pyramid for the GimpProjection. An image pyramid
caches a projection at several sizes, causing the rendering code not to
have to swap in all tiles of a (potentially) large image; it can use
small versions of the projection if the user is zoomed out.
The image pyramid also imroves visual quality, especially at zoom levels
where there is a pyramid level that matches perfectly (i.e. at e.g. 50%,
25%, and 12.5% zoom). A step on the right track for bug #76096.
* app/core/gimpprojection.[ch]: Adjusted to make use of an image
pyramid. GimpProjection now keeps an array of TileManager:s, one per
pyramid level. Renamed _alloc_tiles to _alloc_levels.
* app/display/gimpdisplayshell-draw.c: (gimp_display_shell_draw_area):
Use the right GimpProjection level when drawing
* app/display/gimpdisplayshell-render.c: (render_image_init_info_full):
