# Objective
Fixes [#10061]
## Solution
Renamed `RenderInstance` to `ExtractInstance`, `RenderInstances` to
`ExtractedInstances` and `RenderInstancePlugin` to
`ExtractInstancesPlugin`
# Objective
Currently, the only way for custom components that participate in
rendering to opt into the higher-performance extraction method in #9903
is to implement the `RenderInstances` data structure and the extraction
logic manually. This is inconvenient compared to the `ExtractComponent`
API.
## Solution
This commit creates a new `RenderInstance` trait that mirrors the
existing `ExtractComponent` method but uses the higher-performance
approach that #9903 uses. Additionally, `RenderInstance` is more
flexible than `ExtractComponent`, because it can extract multiple
components at once. This makes high-performance rendering components
essentially as easy to write as the existing ones based on component
extraction.

## Changelog
### Added
A new `RenderInstance` trait is available mirroring `ExtractComponent`,
but using a higher-performance method to extract one or more components
to the render world. If you have custom components that rendering takes
into account, you may consider migration from `ExtractComponent` to
`RenderInstance` for higher performance.
