- Consider DPI of QgsWmsRenderContext what is the OGC default (0.28 mm per pixel) or the passed WMS parameter - this is done by creating the QgsRenderContext by the mapSettings (with BBOX) or applying the dotsPerMm to the scaleFactor. - Additionally the image size needs to be calculated according to the QgsRenderContext now, what means it needs to be generated before. - The QPainter needs to be applied after to the context (since it's not passed by creating the context anymore).
… context settings according to the mapSettings since it NEVER has a BBOX (since of RULE)
…correct CRS and care about meter based crs. This fixes #50366
…labels and having not yet a fix font with "LAYERFONTBOLD": "TRUE", "LAYERFONTSIZE": "12", "LAYERFONTFAMILY": self.fontFamily, "ITEMFONTBOLD": "TRUE", "ITEMFONTSIZE": "12", "ITEMFONTFAMILY": self.fontFamily
