+// This is how grids are handled. On the application side,
+// things are mostly handled this way. Web browsers, etc
+//
+// On the toolkit side, this must be translated into the display
+// code. This is particularly complicated with ncurses but once
+// done in the toolkits, bears fruit in the application code simplicity
+
+// NOTE: X numbers horizontally, Y is numbered down. Like in mathematics, EXCEPT Y IS DOWN
+// this is the only sensible way. It's way too confusing to use negative numbers for Y.
+// This is an attempt to make it simple for people to program against this code,
+// then we hide these implementation details in the toolkit plugins
+
+// Grid numbering examples (H) or (W,H)
