Tech: Investigate three.js native text rendering as a replacement for FloorLabels

[phanlezz]

Research

Our current approach to the floor labels has some issues to it (primarily clipping and weird font size choices) that might get resolved through an implementation with three.js native text elements.

This would likely fix the issue with flickering labels, clean-up the code base (the native calls are probably more compact and easier to understand) and might bring a performance boost with it. Along with the option for more stylistic choices (like 3D-Text).

General Idea

• Investigate three.js text elements
• Swap existing canvas-based calls with three.js calls
• Evaluate new aesthetic with other contributors
