SUMMARY
The `Krita::documents()` method returns a `QList<Document*>`. When called from
a Python plugin, all the `Document*` are leaked.
STEPS TO REPRODUCE
1. Open the scripter
2. Run
```
for i in range(100000):
docs = Krita.instance().documents()
```
OBSERVED RESULT
Heap usage rises permanently
EXPECTED RESULT
Heap usage stays stable
SOFTWARE/OS VERSIONS
Windows:
macOS:
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma:
KDE Plasma Version:
KDE Frameworks Version:
Qt Version: 5.15.14
ADDITIONAL INFORMATION
`documents()` is defined as `QList<Document *> documents() const /Factory/;`.
But a `QList<*>` cannot track ownership. `/Factory/` just communicates that the
caller owns the `QList`, but `QList` cleanup won't (can't!) clean up the
`Document*`s. The method should probably return a
`QList<QScopedPointer<Document>>`?
