or size properties
Previously only string values of the format 'x,y' would be permitted. But
I've seen MANY bug reports and questions about this, so also allow
arrays of doubles as a valid result. E.g. "array(3,5)". In any case, it's
just nicer.
Fixes#31444
Adds data defined control over layout map grid:
- enabled state
- interval X/Y
- offset X/Y
- frame size and margin
- annotation distance from frame
- cross size
- frame line thickness

Allow path preprocessors to be chained and don't force replace
any existing ones.
Processors can be removed via a call to QgsPathResolver::removePathPreprocessor,
using the unique ID returned by the original call to setPathPreprocessor
