Custom 8th wall three pipeline module, which fixes a problem with the camera's projectionMatrixInverse. See line 33 for the fix.
// Custom three pipeline module because 8th wall's doesn't allow for custom renderer config
// also it has problems with raycasting when using three >= r103 because of this PR:
// https://github.com/mrdoob/three.js/pull/15996
