313 * To add a transformation to a surface, create a struct weston_transform, and
314 * add it to the list surface->geometry.transformation_list. Whenever you
315 * change the list, anything under surface->geometry, or anything in the
316 * weston_transforms linked into the list, you must set
317 * surface->geometry.dirty = 1.
319 * The order in the list defines the order of transformations. Let the list
320 * contain the transformation matrices M1, ..., Mn as head to tail. The
321 * transformation is applied to surface-local coordinate vector p as
322 * P = Mn * ... * M2 * M1 * p
323 * to produce the global coordinate vector P. The total transform
325 * is cached in surface->transform.matrix, and the inverse of it in
326 * surface->transform.inverse.
328 * The list always contains surface->transform.position transformation, which
329 * is the translation by surface->geometry.x and y.
331 * If you want to apply a transformation in local coordinates, add your
332 * weston_transform to the head of the list. If you want to apply a
333 * transformation in global coordinates, add it to the tail of the list.
