+            * not be redrawn at all. Accordingly, we must not
+            * paint any character cell in a WM_PAINT context which
+            * already has a pending update due to terminal output.
+            * The simplest solution to this - and many, many

+            * not to do any actual painting at _all_ if there's a

+            * character cells as INVALID and wait for the
+            * scheduled full update to sort it out.
+            * 
+            * I have a suspicion this isn't the _right_ solution.
+            * An alternative approach would be to have terminal.c
+            * separately track what _should_ be on the terminal
+            * screen and what _is_ on the terminal screen, and
+            * have two completely different types of redraw (one
+            * for full updates, which syncs the former with the
+            * terminal itself, and one for WM_PAINT which syncs
+            * the latter with the former); yet another possibility
+            * would be to have the Windows front end do what the
+            * GTK one already does, and maintain a bitmap of the
+            * current terminal appearance so that WM_PAINT becomes
+            * completely trivial. However, this should do for now.
