* it can be overridden in CSS files by enforcing a #GtkThemingEngine
|

* object to be loaded as a module.

*
|
|
* In order to implement a theming engine, a #GtkThemingEngine subclass
|
|
* must be created, alongside the CSS file that will reference it, the
|
|
* theming engine would be created as an .so library, and installed in
|
|
* $(gtk-modules-dir)/theming-engines/.
