/*

|

Each custom component is secretly modified to have an extra state and id.
|
||||
When there is an HMR update, this state is changed, forcing it to re-render.
|
||||
|
||||
Each *user-created* React.useState is secretly modified and accompanied by an ID.
|
||||
Every time its state is set, the HMR.statesNew map for this ID is set to contain the new state and updater.
|
||||
When a component is removed, any of it's states in HMR.statesNew are also removed.
|
||||
(HMR.statesNew is the "running total" of all states currently at play).
|
||||
|
||||
---
|
||||
|
||||
When a state is interacted with:
|
||||
- statesNew for this id is set
|
||||
- the internal state is also set in the traditional way
|
||||
|
||||
When there is an HMR update:
|
||||
- All custom components are re-rendered...
|
||||
for each useState(value) call that then happens in the re-render:
|
||||
- if there is a "statesOld" value for this state, use that and ignore the passed value, otherwise use the passed value
|
||||
- if this state has not been interacted with since the last reload (statesNew is empty at this id), set statesNew<id> with whatever is in statesOld<id>
|
||||
- statesNew is moved into *statesOld*
|
||||
- statesNew is cleared.
