  Occasionally introducing changes that are breaking the API. The breakage are generally minor and easy to fix.
  Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
  
+ - 2015/05/31 (1.39) - renamed IsRectClipped to IsRectVisible for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete).
  - 2015/05/27 (1.39) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons.
  - 2015/05/11 (1.39) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "opened" state of a popup. BeginPopup() returns true if the popup is opened.
  - 2015/05/03 (1.39) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
