Breps coming from Rhino produce RawData value that includes doc-specific garbage, generating different hashes for Breps that are geometrically identical.

• I've read the contribution guidelines!

Expected Behaviour

The RawData value should be the same.

Actual Behaviour

Breps coming from Rhino produce RawData value that includes doc-specific garbage, generating different hashes. This prevents consistent diffing mechanism: e.g. diffing two Streams containing identical Breps coming from two different Rhino docs produces an unexpected response where objects that should be identical are actually different.

Affected Projects

SpeckleServer (StreamDiff)

Reproduction Steps & System Config (win, osx, web, etc.)

Rhino 6 & Win 10

Proposed Solution (if any)

As the RawData value can't really be changed for Breps for the moment, the diffing mechanism for Breps should operate on their display value (which will remain identical), and not the RawData value.
