365 * change the list, anything under surface->geometry, or anything in the
366 * weston_transforms linked into the list, you must set
367 * surface->geometry.dirty = 1.
369 * The order in the list defines the order of transformations. Let the list
370 * contain the transformation matrices M1, ..., Mn as head to tail. The
371 * transformation is applied to surface-local coordinate vector p as
372 * P = Mn * ... * M2 * M1 * p
373 * to produce the global coordinate vector P. The total transform
375 * is cached in surface->transform.matrix, and the inverse of it in
376 * surface->transform.inverse.
378 * The list always contains surface->transform.position transformation, which
379 * is the translation by surface->geometry.x and y.
381 * If you want to apply a transformation in local coordinates, add your
382 * weston_transform to the head of the list. If you want to apply a
383 * transformation in global coordinates, add it to the tail of the list.
