+ * Grid type config options available in Loopy.
+ *
+ * Annoyingly, we have to use an enum here which doesn't match up
+ * exactly to the grid-type enum in grid.h. Values in params->types
+ * are given by names such as LOOPY_GRID_SQUARE, which shouldn't be
+ * confused with GRID_SQUARE which is the value you pass to grid_new()
+ * and friends. So beware!
+ *
+ * (This is partly for historical reasons - Loopy's version of the
+ * enum is encoded in game parameter strings, so we keep it for
+ * backwards compatibility. But also, we need to store additional data
+ * here alongside each enum value, such as names for the presets menu,
+ * which isn't stored in grid.h; so we have to have our own list macro
+ * here anyway, and C doesn't make it easy to enforce that that lines
+ * up exactly with grid.h.)
+ *
+ * Do not add values to this list _except_ at the end, or old game ids
+ * will stop working!
