/**
* Authoritative op list, used for generating the op ID enum, ID based LUTS, and
* the functions to which they dispatch. Parameter macros are executed for each op,
* in order, based on the op's type.
*
* There are 4 types of op, which defines dispatch/LUT capability:
*
* | DisplayList | Render | Merge |
* -------------|-------------|-------------|-------------|
* PRE RENDER | Yes | | |
* RENDER ONLY | | Yes | |
* UNMERGEABLE | Yes | Yes | |
* MERGEABLE | Yes | Yes | Yes |
*
* PRE RENDER - These ops are recorded into DisplayLists, but can't be directly rendered. This
* may be because they need to be transformed into other op types (e.g. CirclePropsOp),
* be traversed to access multiple renderable ops within (e.g. RenderNodeOp), or because they
* modify renderbuffer lifecycle, instead of directly rendering content (the various LayerOps).
*
* RENDER ONLY - These ops cannot be recorded into DisplayLists, and are instead implicitly
* constructed from other commands/RenderNode properties. They cannot be merged.
*
* UNMERGEABLE - These ops can be recorded into DisplayLists and rendered directly, but do not
* support merged rendering.
*
* MERGEABLE - These ops can be recorded into DisplayLists and rendered individually, or merged
* under certain circumstances.
