+ These are our vertex-indices for a series of "quads", which we implement
+ as a series of pairs of triangles. See setRectFan() for the
+ vertex order.
+
+ The largest value is 255, so we could store these in any size
+ (byte, short, int). Since the table is small, we just choose the size
+ that we think will be fastest (e.g. some drivers don't have native support
+ for byte-indices, so byte may not be the fastest)
