#1139 Fix for world going black/white in some scenes (NaNs) (#1273)

* #1139 Fix for world going black/white in some scenes (NaNs)

NaNs were coming from normal encode/decode.  Take advantage of available gbuffer space to send full normal instead of encoding.

* #1139 Cleanup

remove now unused encodeNormF.glsl

* #1139 Remove final reference to encodeNormF

* #1139 Fix for getNormalEnvIntensityFlags referencing wrong sampler for env intensity

* Mac build fix
