265 * To add a transformation to a surface, create a struct weston_transform, and
266 * add it to the list surface->geometry.transformation_list. Whenever you
267 * change the list, anything under surface->geometry, or anything in the
268 * weston_transforms linked into the list, you must set
269 * surface->geometry.dirty = 1.
271 * The order in the list defines the order of transformations. Let the list
272 * contain the transformation matrices M1, ..., Mn as head to tail. The
273 * transformation is applied to surface-local coordinate vector p as
274 * P = Mn * ... * M2 * M1 * p
275 * to produce the global coordinate vector P. The total transform
277 * is cached in surface->transform.matrix, and the inverse of it in
278 * surface->transform.inverse.
280 * The list always contains surface->transform.position transformation, which
281 * is the translation by surface->geometry.x and y.
283 * If you want to apply a transformation in local coordinates, add your
284 * weston_transform to the head of the list. If you want to apply a
285 * transformation in global coordinates, add it to the tail of the list.
