Implement 4x4 matrix inversion based on LU-decomposition with partial pivoting. Instead of simply computing the inverse matrix explicitly, introduce the type struct weston_inverse_matrix for storing the LU-decomposition and the permutation from pivoting. Using doubles, this struct has greater precision than struct weston_matrix. If you need only few (less than 5, presumably) multiplications with the inverse matrix, is it cheaper to use weston_inverse_matrix, and not compute the inverse matrix explicitly into a weston_matrix.

Wayland Demos This repository contains a few demos application for the Wayland project. There's a sample compositor that can run on KMS, under X11 or under another Wayland compositor and there's a handful of simple clients that demonstrate various aspects of Wayland:
