Add 360 Panorama Player, fix bug with TexImage2D Wrapping

[DanielSturk]

PanoramaLayerCompositor extends LayerCompositor

• Controlled by FOV and angle
• Supports Image Fit Mode
• Only a minimal change to LayerCompositor to make it extendable for this

Fixed tiny bug with vertical wrapping in TexImage2D

Built on top of this unmerged PR unfortunately https://github.com/threeify/threeify/pull/270

there's an horizontal flip, fixed it with: makeMatrix4Scale(new Vector3(1, 1, -1)), and updated it to version 1.89.0-alpha.5
