And API mechanism to propagate these from layout exports down
to the render context
Gives us a place to specify fine-tuned control over masking
settings for map renders
If the 'map/maskBackend' QSettings key is set to 'geometry', then
QgsGeometryPaintEngine will be used for calculating clip paths
for label masking instead of QPainterPath
The intention here is that we gain improved flexibility to optimise
the creation and logic behind clipping path generation, vs the
limited API we get from QPainterPath.
The original workaround was only supposed to apply to QList/
QVector of QVariantMaps. By replacing them all in sip we
break mapping of signals defined in c++ which are emitted
by Python code.
Fixes exceptions after running processing algorithms in Qt6
builds.
