 - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius.
 - Limiting Columns()/BeginColumns() api to 64 columns with an assert. While the current code

+- InputText: Fix corruption or crash when executing undo after clearing input with ESC, as a

+- InputText: Fix using a combination of _CallbackResize (e.g. for std::string binding), along with the
+  _EnterReturnsTrue flag along with the rarely used property of using an InputText without persisting
