Perspective HUD Attachment Points

Please introduce a new set of HUD attachment points with perspective rendering capabilities, allowing for HUD objects to have depth and Physically-Based Rendering (PBR) lighting effects on HUD elements.

Current Situation:

At present, Second Life offers a series of attachment points for the HUD (e.g., bottom, bottom left, center, center2, etc.). These HUD elements are rendered as though they are attached to the view camera using an orthographic perspective. This limits the ability to incorporate depth and advanced lighting effects into HUD designs. Eg, if I want to draw shiny spinning gold coins on a game interface, they look flat and solid yellow.

Proposed Enhancement:

Add a new set of HUD attachment points that prepend "Perspective" to their names (e.g., Perspective Bottom, Perspective Bottom Left, Perspective Center, Perspective Center2, etc.). These attachment points will render HUD elements in a perspective frame, enabling designers to leverage depth and PBR lighting effects.

Positives:

• Allows for more immersive and visually appealing HUD designs by incorporating depth and realistic lighting.

• Provides designers with the option to choose between orthographic and perspective rendering based on their specific needs and creative vision.

• Makes HUD elements in 3D Secondlife look like 3D things!

No source files, tests, or entry points are named in the issue. Begin by locating the viewer's existing HUD attachment-point and rendering implementation; done means adding the requested Perspective attachment-point set and enabling depth and PBR lighting while preserving the existing orthographic options.
