+// Debug tools : dump the layers tree in a file.
+// The format is simple:
+// properties have the form: key = value;
+// all statements are finished with a semi-colon.
+// value can be:
+// - int
+// - float
+// - array of elements
+// - composed type
+// a composed type enclose properties in { and }
+// an array enclose composed types in { }, separated with a comma.
+// exemple:
+// {
+//   x = 3;
+//   y = 4;
+//   value = {
+//     x = 3;
+//     y = 4;
+//   };
