3a756e200f Remove medium samples from RaySamples used in wavefront integrator. 
The previous implementation would inadvertently reuse the same sample value
for medium distance sampling when rays passed through interfaces between
different scattering media. In turn, this led to significant errors in
rendered images.

See issue #221...

d013ea7e9d Issue a more-friendly error if an unsupported camera is used with a bidir integrator. 
There's no need for the user to see a fatal error, which should be reserved
for an actual internal error rather than a problem with the scene as
specified...

Issue #279.

Add a option to use arbitrary names for grids

cdccb71cb1 Fix handling of interface materials in Path and SimplePath integrators 
For these, if a ray goes through an interface we need to treat the interface
as specular. (This is needed since the shadow ray test used in these
integrators does not handle interfaces but just returns false for shadow
rays that hit them.) Related to #271.

dbd005ac52 Fix bug in updateMaterialNeeds()'s detection of interface materials 
*haveMedia would never be set to true due to a check for a nullptr material
at the start of the function... In turn, this led to the wavefront integrator not
detecting the case of interface materials without participating media, which
still requires special handling for direct lighting to come out right.

This should fix #271.

19336a6c7f Fix bug with CPU writing to managed memory while OptiX is creating BVHs 
On Windows, both CPU and GPU can't write to managed memory at the same time.
Previously, it was possible that the asynchronous creation of the sampler, camera,
film, etc., could still be running when OptiX BVH construction started. This was
especially likely with the Halton sampler + random digit permutations, which take
a while to initialize.

Fixes #246.
