Canvatorium Lab 051

Adding a simple tooltip for the image on the main window.

The tooltip will appear above the window on hover.

I ran into an alpha render order issue while working in this lab. It’s a quirk of the transparent 2D GUI and how Babylon JS renders transparent items. To work around it I positioned the tooltip above the main window.

I have a few other ideas for tooltips that I may explore in future labs.

1. The tooltip appears anchored to the hand or controller, close to the player
2. The tooltip appears in a fixed position relative to the player, similar to subtitles in a VR game.
