|
* - the objects IDs (hashes) are identical.
|
|
*
|
|
* Note that we only compare with the immediately preceding (newer) revision,
|
|
* so branches and merges can disrupt caching.
|
|
*
|
|
* Possible optimizations:
|
|
* - if we record which child sheets a sheet has, we could also clone it,
|
|
* without having to parse it. However, this is somewhat complex and may
|
|
* not save all that much time.
|
|
* - we could record what libraries a sheet uses, and parse only if one of
|
|
* these has changed (benefits scenarios with many library files),
|
|
* - we could record what components a sheet uses, and parse only if one of
|
|
* these has changed (benefits scenarios with few big libraries),
|
|
* - we could postpone library lookups to render time.
|
|
* - we could record IDs globally, which would help to avoid tripping over
|
|
* branches and merges.
