env_map_rot parameter affect on hybrid RT/PT renderer

[arconovum]

I noticed this in my API and decided to test it on your json scene files if it repeated the same issue. This is just a heads up, you can decide if its an issue for you or not.

if as a user while modifying manually a json scenefile accidentally forgets to remove (or set to 0 , assuming not tested) 'env_map_rot' when 'env_map' is set to 'physical sky' will have no affect in RT , but when you switch over to PT , this value will shift the sun position slightly .

example:
"environment": {
"env_map": "physical_sky",
"env_map_rot": 40.0,
},

Good catch, it should have been ignored in both. Fixed in sergcpp/Ray#133
