I'm creating a new theme based on formal white. The formal white config file includes:
$THEME->custompix = true;
/// If true, then this theme must have a "pix"
/// subdirectory that contains copies of all
/// files from the moodle/pix directory, plus a
/// "pix/mod" directory containing all the icons
/// for all the activity modules.
I'm creating a new theme. There are lots of folders under /mod. Do I need to include all folders and all files? or all folders and graphic files only?
