Displacement values >1.0 and <0.0 produce geometry bugs

[vicnaum]

The thread https://forum.corona-renderer.com/index.php?topic=5104 led to this bug:

1) Camera subdivision doesn't take displacement map values >1.0 into account:

Noise Map: Output 10.0, Corona Displacement: 20cm


Noise Map: Output 1.0, Corona Displacement: 200cm


2) Displacement map values lower than 0.0 just cut:

Noise: Output 1.0, RGB Offset: -0.5



And please don't ask why I did that... Some generators (like PhoenixFDOceanTex) can have any values, not limited to 0.0-1.0.
Modifier "Displace" is working correctly with out of range (0.0-1.0) values. Vray is also working correctly with them.

Corona cuts <0, and re-optimises >1.

Displacement just crashes for me. :(

I got also problem with displacment map in corona it noising bumping arround the scenes

fixed both issues
