347 * change the list, anything under surface->geometry, or anything in the
348 * weston_transforms linked into the list, you must set
349 * surface->geometry.dirty = 1.
351 * The order in the list defines the order of transformations. Let the list
352 * contain the transformation matrices M1, ..., Mn as head to tail. The
353 * transformation is applied to surface-local coordinate vector p as
354 * P = Mn * ... * M2 * M1 * p
355 * to produce the global coordinate vector P. The total transform
357 * is cached in surface->transform.matrix, and the inverse of it in
358 * surface->transform.inverse.
360 * The list always contains surface->transform.position transformation, which
361 * is the translation by surface->geometry.x and y.
363 * If you want to apply a transformation in local coordinates, add your
364 * weston_transform to the head of the list. If you want to apply a
365 * transformation in global coordinates, add it to the tail of the list.
