251 /* Using weston_surface transformations
253 * To add a transformation to a surface, create a struct weston_transform, and
254 * add it to the list surface->geometry.transformation_list. Whenever you
255 * change the list, anything under surface->geometry, or anything in the
256 * weston_transforms linked into the list, you must set
257 * surface->geometry.dirty = 1.
259 * The order in the list defines the order of transformations. Let the list
260 * contain the transformation matrices M1, ..., Mn as head to tail. The
261 * transformation is applied to surface-local coordinate vector p as
262 * P = Mn * ... * M2 * M1 * p
263 * to produce the global coordinate vector P. The total transform
265 * is cached in surface->transform.matrix, and the inverse of it in
266 * surface->transform.inverse.
268 * The list always contains surface->transform.position transformation, which
269 * is the translation by surface->geometry.x and y.
271 * If you want to apply a transformation in local coordinates, add your
272 * weston_transform to the head of the list. If you want to apply a
273 * transformation in global coordinates, add it to the tail of the list.
