3 months ago: Spent some time fussing over the impending llGetAspectRatio() function before concluding that, since it evidently only reports mouselook AR, it can't really be used in the current ARES tutorial screen calibration process. Maybe in the future once display is implemented this will be useful, as display will introduce an interactive UI anchor setup mode (as seen in Unity, Godot, Unreal, and... yes, ElvUI)
