OpNode evaluation function now needs to know about what the evaluation context is

Move evaluation context type enum to external-facing depsgraph header

Added stubs for freeing evaluation contexts

Fleshing out entrypoint for evaluation context creation

Changed Components to store a stack of different contexts they can use

XXX: This code may still need to be modified before it will compile

Start of draft code to initialise evaluation contexts

Replacing geometry eval callbacks with proper new stubs for each type

Rename evaluation context freeing API method to make it clearer that multiple contexts are being freed

Code reshuffling - Move context management decls before evaluation entrypoint funcs

Evaluation entrypoints now need to know what contexts they are to be evaluating

This is necessary to ensure that just the right set of values end up
getting evlauated

Compile Fix - Type Typo

When adding new nodes to the graph, they need to be added to the op_nodes list

This allows us to keep track of all the nodes which play a part in
the evaluation process.

Reshuffle order of creating root node so that it is first

Fleshing out operation eval contexts - for separate Viewport/Render/Bake eval steps

For each of these different situations, we need to have separate copies
of the data hanging around, allowing us to render with different geometry
data copies, etc. which solves our state/data dilemas.

Stub for evaluating mesh geometry

Add some ptr data to some more operations

Setting Pose PointerRNA for pose eval operations

Surface and Lattice Eval Ops

Stubbed in evaluation operation node for metaball evaluation

From the looks of things so far, it seems that only "motherball"
metas can be evaluated. Other metaballs are evaluated at the same
time that the motherball gets done.

Set PointerRNA data for obdata eval operations
