It's almost never useful to have a bitmask here, since it's only used
for the intersection case in gtk_css_style_provider_lookup. However,
even if that returns true, we still need to check every single style
property for being set again in the look afterwards.
Just remove the bitmask.
We don't want to return a GFile because GFile can't handle can't deal
with data: urls.
That makes the code a bit more complicated that doesn't deal with those
URLs, but it makes the other code actually work.
GtkCssImageUrl also now decodes data urls immediately instead of only at
the first load. So don't use data urls if you care about performance.
When looking for versioned theme files, we were
looking for directories names gtk-4.x for x
bigger than 14, which mades sense for GTK 3,
but we are starting out at 0 again, so remove
this check.
gtk_css_provider_get_named() is the old GTK3 style API to load themes.
Instead, export the function we currently use,
gtk_css_provider_load_named().
As a side effect we allow people to load a theme as often as they want
without conflicting with GTK's theme.
Emit all errors via the parser, don't try to have a custom error
handling machinery.
The only exception is the initial file load error - we need to do that
one directly, because there is no parser.
This commit is still way too big, but I couldn't make it smaller.
It transitions the old CSS parser to the new parser. CSS parsing is now
tokenized, everything else is probably still buggy.
This is ithe first step towards converting the parsing code to use
tokens. For now, the topken type is just a magic enum value that only
works as-needed.
This library is meant to be the new CSS library that gets used from GDK,
GSK and GTK for string printing and parsing.
As a first step, move GtkCssProviderError into it.
While doing so, split it into GtkCssParserError (for critical problems)
and GtkCssParserWarning (for non-critical problems).
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.
commit 475d916eb9 added various paths that
use theme-name for this, but the existing path already used THEME, with
a subsequent description referring to the latter. So use that everywhere
This is just lots of renaming.
The interface remains private, so the public API does not change, apart
from removing the definition of the Interface object to avoid
subclassing.
When loading a per-theme settings.ini file, look for it in
the same directory where we found the gtk.css file for the
theme. Previously, we were always looking in
$prefix/share/themes/THEME/gtk-3.0/, even if the css was
loaded from somewhere else.

With this change, we now look in
$XDG_DATA_HOME/themes/THEME/gtk-3.x
$HOME/.themes/THEME/gtk-3.x
$XDG_DATA_DIRS/themes/THEME/gtk-3.x
GTK_DATA_PREFIX/themes/THEME/gtk-3.x
