In addition to adding in theme usage reports, there is also the
addition of an icon on the theme cards which takes you to the report.
This icon only appears for that theme if it has been used in any
overriding context.
The $CFG->svgicons setting was introduced in Moodle 2.4 due to incomplete
SVG support in certain web browsers.
The landscape has evolved significantly since then, and all modern browsers
now handle SVG files correctly.
The $CFG->svgicons settings has been removed and the supports_svg() method
has been updated with currently supported browsers (IE support was removed
in Moodle 3.10).
In PHP 8.2 and later, setting a value to an undeclared class property is
deprecated and emits a deprecation notice.
So we need to add missing class properties that still need to be declared.
Editor stylesheets are kept separately to standard plugin stylesheets so
that they can be provided to style individual iframes where loading the
standard Moodle stylesheets would be incorrect.
Unfortunately the editor stylesheet system does not consider that
subplugins may want to add small individual styling to the editor but
this is required in some situations.
Fixes the resolve_image_location function, which previously returned
the 'icon' or 'monologo' icon for modules, no matter the requested
image name.
Also fixes an incorrect pix_icon() call for the context header, which
was hidden by the faulty resolve function.
* The fact that non-existing strings are returned in certain format
starting with the bracket, is kind of side debugging effect. The value
is really undefined and should not be relied upon.
* The string could actually exist and be worded so that its first
character is also the square bracket.
This still allows child themes to override editor_scss, but will fall
back to what the parent is using if they do not specify it. This
negates the need for every child them to have the config duplicated
in order to utilise it.
As a part of the removal of bootstrapbase & clean
I removed some logic that got the base config of bootstrapbase,
this should of been changed to get boosts config.

Themes that have the function theme_themename_alter_css_urls() in lib.php
can change the css url from theme/styles.php to a local script like
theme/themename/css.php. The local css.php file can be used to serve
various versions of the theme css, for example versions compiled using
different scss variables.
There is no point pre-compiling the theme SCSS if it is not stored somewhere that is available
to all webserving nodes. Localcache needs to be backed by the MUC cache.
