Rewrite some of the depth testing for the raymarcher #17

currently its using an SDF box raymarch to get the distance into the domain and to the domain. also seems to cause a few bugs. especially with custom domain sizes.

Used a second shader pass with cull back and took the difference with cull front in the main raymarch pass
