Jehan 32740ac0de app: improve alpha to selection with multiple items.
I created a new function gimp_channel_combine_items() which combines a
list of items with a channel. The list of items is first combined
together as an union set, then only combined with the channel with the
desired operation (this is important for operations such as intersect
which was broken in my previous commit because all items would be
intersected with each other and the selection, whereas we actually want
the union of all items to be intersected with the selection). This new
function is now used for "Alpha to Selection".

Also similarly to copy or color-pick on multi-layers, alpha to selection
will now use the composited result of the multi-layers as visible. In
particular it means that opacity, modes and visible properties on the
layers are taken into account. Alpha to selection on a single layer
though still works as previously, only taking the non-composited layer
data into account.
I am actually struggling if alpha to selection on uncomposited layers
(just an union on alpha to selection result for each layer) would not
make sense to on some workflows. To be experimented.

Finally it is to be noted that this function should also work on
channels and vectors (both single or multiple; and of course in such
cases, compositing does not matter) though I haven't tested yet. It
could even work with a source mix of layers, channels and vectors,
though our GUI does not allow such action currently.

README

                   ------------------------------
                   GNU Image Manipulation Program
                      2.99 Development Branch
                   ------------------------------

This is an unstable development release, an intermediate state on the
way to the next stable release: GIMP 3. GIMP 2.99 may or may not do what
you expect. Save your work early and often. If you want a stable
version, please use GIMP 2.10 instead.

If you think you found a bug in this version, please make sure that it
hasn't been reported earlier and that it is not just new stuff that is
still being worked on and obviously not quite finished yet.

If you want to hack on GIMP, please read the file HACKING. For
detailed installation instructions, see the file INSTALL.


1. Web Resources
================

GIMP's home page is at:

	https://www.gimp.org/

Please be sure to visit this site for information, documentation,
tutorials, news, etc.  All things GIMP-ish are available from there.

There you can get the latest versions of plug-ins, using a convenient
forms-based interface.

The latest version of GIMP can be found at:

	https://www.gimp.org/downloads/


2. Mailing Lists
================

We have several mailing lists dedicated to GIMP user and development
discussion.  There is more info at

	https://www.gimp.org/mail_lists.html

Links to several archives of the mailing lists are included in that page.

Gimp-user-list is a mailing list dedicated to user problems, hints and
tips, discussion of cool effects, etc.  Gimp-developer-list is oriented
to GIMP core and plug-in developers.  Gimp-gui-list is for discussing
about GIMP interface to improve user experience. Most people will only
want to be subscribed to gimp-user-list. If you want to help develop
GIMP, the gimp-developer mailing list is a good starting point; if you
want to help with GUI design, the gimp-gui list is where you want to
subscribe.


3. IRC
======

And finally, for the real junkies, there is an IRC channel devoted to
GIMP. On GIMPNet (a private free software oriented network) there is
#gimp.  Many of the developers hang out there.  Some of the GIMPNet
servers are:

	irc.gimp.org:6667
	irc.us.gimp.org:6667
	irc.eu.gimp.org:6667


4. Customizing
==============

The look of GIMP's interface can be customized like any other GTK+ app
by editing files in `${XDG_CONFIG_HOME}/gtk-3.0/` (settings.ini and
gtk.css in particular) or by using "themes" (ready-made customizations).
Additionally, GIMP reads `${XDG_CONFIG_HOME}/GIMP/2.99/gimp.css` so you
can have settings that only apply to GIMP.

Included is a set of keybindings similar to those in Adobe Photoshop.
You can find them in the ps-menurc file.  To use them, copy this file
to `${XDG_CONFIG_HOME}/GIMP/2.99/menurc`. You can also manually change
the keybindings to any of your choice by editing:
`${XDG_CONFIG_HOME}/GIMP/2.99/menurc`.
