Fixed scalar_redraw to check if glist is visible; moved 'data' doc and

updated it somewhat.

+#X text 3 67 This subpatch acts as a template which describes the data
+structure. The "struct" specifies four floating point values named
+x \, y \, z \, and q. The "filledpolygon" is a drawing instruction.
+Templates should have only one template object but may have any number
+of drawing instructions.;

+#X text 37 124 When the data window is locked (not in edit mode) you
+can drag the apex of either triangle up or down to change the altitude
+(you should see the cursor change with dragging is meaningful.) In
+edit (unlocked) mode \, you can move teh entire triangles around \,
+or cut \, copy \, and paste them.;

+#X text 37 281 Data is not persistent. If you save a Pd patch and reopen
+it \, the "data" isn't preserved.;
+#X text 37 5 This patch shows a simple data window with two objects
+in it. The objects' data structures and appearances are defined by
+the "template1" subpatch. This kind of object is called a "scalar."
+;
+#X text 37 207 Scalars are described by "templates" \, which are subwindows.
+The subwindows are found by their name \, in this case "template1."
+The template describes what form the data take and how it is shown.
+It's possible to mix data of many different templates in the same collection.
