*	Apply the rotation in Penrose grid descriptions by rotating in the	Simon Tatham	2011-05-06
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	4-vector representation, rather than mucking about with sines and cosines after grid generation. _Should_ make no difference in the generated grids (there's a theoretical risk of an unlucky rounding error just about managing to push some point in or out of bounds, but I think it's vanishingly small), but simplifies the coordinate- flattening procedure, and in particular increases its chance of getting vertical lines actually vertical. (Prior to this change, the game ID 10x10t12:G2554,-31,108_a3b12h0a212a3d102b2a23a2e3b01b0a2c2a0c0 was generating a not-quite-vertical edge at top left, in the Java port but not on Linux; I suspect differences in sin and cos as the cause of the discrepancy. With the rotation done like this, the points' x-coordinates are now computed without reference to their y-coordinates.) [originally from svn r9168]

*	From James Harvey (via a period of collaborative polishing), a patch	Simon Tatham	2011-04-24
	to add two kinds of Penrose tiling to the grid types supported by Loopy. This has involved a certain amount of infrastructure work, because of course the whole point of Penrose tilings is that they don't have to be the same every time: so now grid.c has grown the capacity to describe its grids as strings, and reconstitute them from those string descriptions. Hence a Penrose Loopy game description consists of a string identifying a particular piece of Penrose tiling, followed by the normal Loopy clue encoding. All the existing grid types decline to provide a grid description string, so their Loopy game descriptions have not changed encoding. [originally from svn r9159]
