379 * weston_transforms linked into the list, you must set

384 * transformation is applied to surface-local coordinate vector p as
385 * P = Mn * ... * M2 * M1 * p
386 * to produce the global coordinate vector P. The total transform
388 * is cached in surface->transform.matrix, and the inverse of it in
389 * surface->transform.inverse.
391 * The list always contains surface->transform.position transformation, which
392 * is the translation by surface->geometry.x and y.
394 * If you want to apply a transformation in local coordinates, add your
395 * weston_transform to the head of the list. If you want to apply a
396 * transformation in global coordinates, add it to the tail of the list.
