Add links from gtk_icon_theme_list_contexts() to
gtk_icon_theme_list_icons(), and from there to the Icon Theme
Specification and the Icon Naming Specification.

For symbolic icons, we prefer symbolics in inherited themes over
generic icons in the theme itself. So far this was implemented
by looking at icon_name[0] and looking that up in inherited themes
if it is symbolic. But with automatic rtl/ltr handling, the first
icon name will always have an -rtl or -ltr suffix, and an icon
with that suffix is not going to exist in most cases. To fix this,
look for shorter icon names too, as long as they are still symbolic.

If the foreground color has an alpha != 1 we used to just pass that into
the svg. This is useful to e.g. render an insensitive icon. However,
that is not an ideal model for symbolics. For instance, if the icon uses
overlapping areas when drawing, expecting these to be opaque then the
transparent color will result in a different alpha value for the overlapping
area. Also, non-foreground symbolic colors are still rendered opaque, and
the recoloring of pngs can't handle transparent colors.
So, instead we extract any alpha from the foreground, render using the
opaque colors and then apply the foreground alpha to the entire result.
This means we get an even transparency, even for other colors, and we
can apply alpha for the pngs too.

If an icon theme has a file called "foo-symbolic.symbolic.png" which
was converted from svg using gtk-encode-symbolic-svg we will read
it in an recolor, allowing symbolic icons without using librsvg.

The Adwaita icon theme ships spinners in a scalable directory
with MaxSize=32 and Scale=1. One way to make them scale up in
hi-dpi would be to add an @2 directory with MaxSize=32 and Scale=2,
but that directory would also be consulted in non hi-dpi situations
and give us an effective spinner max size of 64.
Instead, treat svg icons implicitly as hi-dpi, and scale them
up to MaxSize * 2 when in hi-dpi.
Slapping file:// in front of a path does not guarantee a working
uri (e.g. if you are on windows and the path looks like F:\\...).
Therefore, go back to using g_file_new_for_path if we don't have
to deal with a resource.
This makes it possible to look up icons in resources using
the icon theme api, and should be used as a replacement
for installing icons below $pkgdatadir/icons and adding
that location to the search path.
Make icon lookup from resources work without the extra hicolor
component in the path. It is redundant, since we always treat
builtin icons as part of hicolor anyway.
This functionality is only exercised by gnome-shell, currently.
Therefore, forgetting to copy a field here means an instant
gnome-shell crash :-(. More tests needed.
Recent changes made it a breaking mistake to install symbolic icons
of the wrong size into a theme directory, or into the legacy unthemed
icon location.
Since this change affects many apps, do the extra work to keep these
icons working, but emit warnings, in the hope that this will lead to
cleaning up the mess over time.
Reuse the scale information that we have from loading icons
normally, when loading a symbolic icon, so that we apply the
same size constraints.
This commit assumes that svgs have the nominal size of the
directory they are in, which will be true for all current
symbolic icons.
Previously, we were taking thresholds and min/max sizes into
account when choosing the best theme dir, but when it came
to loading the icon, we always scaled icons from scalable
directories all the way, ignoring the min/max size limits.
This commit changes things around so that we now load icons
in Threshold directories at their nominal size, and scale
icons in Scalable directories only up to the specified limits.
To override this and keep the previous behaviour of scaling
all the way to the desired size, use the GTK_ICON_THEME_FORCE_SIZE
flag.
Add /org/gtk/libgtk/icons as a resource path, and ensure
that we always parse an index.theme file for hicolor which
makes the builtin icons available as part of the hicolor theme.
We add a new API, gtk_icon_theme_add_resource_path, which
can be used to add resource path as a base location for
icon theme content, similar to gtk_icon_theme_append_search_path.
Paradoxically, we were loading svgs at the nominal size when
FORCE_SIZE is specified, while scaling them exactly when it
isn't.

This pushes the initialization of is_svg to an earlier point
when the GtkIconInfo is created. This is needed because an icon
info doesn't necessarily always have a filename that we can later
extract the suffix from. For instance, builtin icons have NULL
filename.

When duplicating the icon_info, we forgot to set is_svg. This meant that
any application that used gtk_icon_info_load_icon_async wouldn't have
is_svg set properly.
This fixes blurry icons in the gnome-shell app picker.
