* no matter of how precise the rules is, so we need to override the theme).
* 2) prepend our custom style to GTK's list while keeping priority to user (which is the
* default), so it gets loaded before real user's ones and so gets overridden by them.
*
* One would normally go for 1 because it's ways simpler and requires less code: you just
* have to add the priorities to your styles, which is a matter of adding a few ":theme" in
* the RC file. However, KDE being a bitch it doesn't set the gtk-theme-name but rather
* directly includes the style to use in a user gtkrc file, which makes the theme have
* "user" priority, hence overriding our styles. So, we cannot set priorities in the RC
* file if we want to support running under KDE, which pretty much leave us with no choice
* but to go with solution 2, which unfortunately requires writing ugly code since GTK
* don't have a gtk_rc_prepend_default_file() function. Thank you very much KDE.
