+
+ This implementation uses the simpler version of the growth
+ algorithm, i.e., if there are no forced vertices, a ran-
+ domly chosen tile is added to a randomly chosen vertex (no
+ preference for those 108 degree angles).
+
+ There are two essential differences to the algorithm pre-
+ sented in the literature: First, we do not allow the
+ tiling to enclose an untiled area. Whenever this is in
+ danger of happening, we just do not add the tile, hoping
+ for a better random choice the next time. Second, when
+ choosing a vertex randomly, we will take one that lies
+ withing the viewport if available. If this seems to cause
+ enclosures in the forced rule case, we will allow invisi-
+ ble vertices to be chosen.
+
+ Tiling is restarted whenever one of the following happens:
+ there are no incomplete vertices within the viewport or
+ the tiling has extended a window's length beyond the edge
+ of the window horizontally or vertically or forced rule
+ choice has failed 100 times due to areas about to become
+ enclosed.
