Resolve paths in symbol layer's properties (if there are any paths).
When saving is true
, paths are converted from absolute to relative, when saving is false
, paths are converted from relative to absolute. This ensures that paths in project files can be relative, but in symbol layer instances the paths are always absolute
Reimplemented from QgsSymbolLayerAbstractMetadata.
