DrawList: Replace "bool close" in drawing functions with flags.

docs/CHANGELOG.txt

@@ -37,6 +37,11 @@ HOW TO UPDATE?
 
 Breaking Changes:
 
+- ImDrawList: upgraded AddPolyline()/PathStroke()'s "bool closed" parameter to use "ImDrawFlags flags".
+  The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.
+      bool closed = false ----> use ImDrawFlags_None, or 0
+      bool closed = true  ----> use ImDrawFlags_Closed
+  Difference may not be noticeable for most but zealous type-checking tools may report a need to change.
 - Style: renamed rarely used style.CircleSegmentMaxError (old default = 1.60f)
   to style.CircleTessellationMaxError (new default = 0.30f) as its meaning changed. (#3808) [@thedmd]

 - IsItemHovered(): fixed return value false positive when used after EndChild(), EndGroup() or widgets using
