Add support for additional platform

We are looking for someone(several) who can modify a lightweight GUI library. It is written in C and you can use XML together with CSS to describe interface, structure and style. It originated from Linux but we wish to use this library together with FreeBSD. We have modified the code so that mouse, keyboard and multi-threading works under the BSD platform. But we wish to get help to successfully integrate the X11 part of the code to support FreeBSD. The code base has several other flaws but the short therm goal is to make the GUI library functional on BSD.
