- TreeNode: Fixed combination of ImGuiTreeNodeFlags_SpanFullWidth and ImGuiTreeNodeFlags_OpenOnArrow

incorrectly locating the arrow hit position to the left of the frame. (#2451, #2438, #1897)

- DragScalar, SliderScalar, InputScalar: Added p_ prefix to parameter that are pointers to the data

to clarify how they are used, and more comments redirecting to the demo code. (#2844)

- Misc: Optimized storage of window settings data (reducing allocation count).
