Description
When using relative output filenames (e.g. for output raster layers) like 'output_raster.tif', the Processing Framework will not turn it into a fully qualified path.
Depending on the ProcessingAlgorithm, the result will be written to the current working directory, e.g. C:\OSGeo4W64_Py3\bin\output_raster.tif (not so nice!), or sometimes the algorithm crashes, because it assumes a full path.
Suggestion: use the QgsApplication::qgisSettingsDirPath() as the root directory, e.g. under Windows this is:
C:\Users\janzandr\AppData\Roaming\QGIS\QGIS3\profiles\default\processing\outputs
In my opinion, if ProcessingAlgorithms can always assume a full path, it makes development much easier and consistent.
