|

- ImDrawData: CmdLists[] array is now an ImVector<> owned by ImDrawData rather
|
||||
than a pointer to internal state.
|
||||
- This makes it easier for user to create their own or append to an existing draw data.
|
||||
(#6406, #4879, #1878)
|
||||
Added a ImDrawData::AddDrawList() helper function to do that. (#6406, #4879, #1878)
|
||||
- This makes it easier to perform a deep-swap instead of a deep-copy, as array
|
||||
ownership is now clear. (#6597, #6475, #6167, #5776, #5109, #4763, #3515, #1860)
|
||||
- Syntax and allocation count are otherwise identical.
