X server resources that should be set.

Booleans are formatted as "true" or "false" respectively.

List elements are recursively formatted as a string and joined by commas.

All other values are directly formatted using builtins.toString.

Note, that 2-dimensional lists are not supported and specifying one will throw an exception.

If this and all other xresources options are
