Internals: Storing settings using ImVec2ih to match what we are doing with dock node. + removed ImMax from reading Size value (done in Begin) + removed seemingly unnecessary FLT_MAX compare in SettingsHandlerWindow_WriteAll.

About: Added backquote to text copied into clipboard so it doesn't mess up with github formatting when pasted.
