The optional scaleFactor parameter can specify a font size scaling factor. It is recommended to set this to QgsTextRenderer::calculateScaleFactorForFormat() and then manually calculations based on the resultant font metrics. Failure to do so will result in poor quality text rendering at small font sizes.
