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