Upgrading to A-Frame 1.5.0

[diarmidmackenzie]

Mostly works with 1.5.0, but upgrading all the examples has revealed a handful of issues.

1. color changes in some examples. This is due to previously bugged code, using A-Frame 1.4.2 and colorManagement: true, calls should be made to applyColorCorrection, when using THREE.js Color() directly. This is handled automatically in 1.5.0. Where these calls were missing, the examples were previously showing the "wrong" colors, and are now correct.

2. physics-ammo.html

Hits error when re-spawning a ball.

ReferenceError: body is not defined

To be investigated under c-frame/aframe-physics-system

3. updates.html & updates-multi-mesh.html

When mesh capacity is updated, a large instance appears at the origin, and frame rate drops (particularly noticeable with the multi-mesh example).

This requires further investigation.

Physics problem is nothing to do with 1.5.0, just a bug in aframe-physics-system - fixed here: c-frame/aframe-physics-system#54

Problem 3 turns out to be a regression in 1.4.0. Issue was instancedMesh.count not being set up correctly on initialization, so additional instances without specified matrices were being rendered.

Problem didn't appear at 1.3.0 - not sure why, but new code should be better for all versions.
