Cleanup messy code during the release of v2.0.0-beta

1

Some parts of the codebase are messed up to quickly support some features: * renderer * static canvas display in studio * estimators these should be cleaned up or refactored

1

Mostly because there is no surface for photons to land on. Photon tracer will keep shooting photons and cannot reach a certain number of recorded photons.

Makes the type of film used by some renderers changeable (by users).

Transform memory management

1

~~Transforms do not occupy memory as much as primitives (unless meshes are created with one-transform-per-primitive basis); we should just pass data around rather than raw pointers.~~

It is unclear for now that who is responsible for the creation of PrimitiveMetadata. Specifically, we need a clear documentation or implementation that clears the following mysteries: 1. Who is...

The structure of Photon's resource system is becoming more and more complex, increasing the risk of smart pointer cyclic reference. Consider using weak_ptr or just raw pointers.
