VERSION 1.62 WIP (IN PROGRESS)
Breaking Changes:
Other Changes:
- Nav: To keep the navigated item in view we also attempt to scroll the parent window as well as the current window. (#787)
- TreeNode: Fixed nodes with ImGuiTreeNodeFlags_Leaf flag always returning true which was meaningless.

- You can use the style editor ImGui::ShowStyleEditor() to browse your fonts and understand what's going on if you have an issue.
- Make sure your font ranges data are persistent (available during the call to GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build().
- Use C++11 u8"my text" syntax to encode literal strings as UTF-8.
- If you want to include a backslash \ character in your string literal, you need to double them e.g. "folder\\filename".
