drawGlyph()

void QgsVectorFieldEngine::drawGlyph	(	const QgsPointXY &	lineStart,
		double	xVal,
		double	yVal,
		double	magnitude )

Draws a single glyph at lineStart, in painter coordinates, using the symbology of the settings the engine was constructed with.

Does nothing for the symbologies which are not drawn glyph by glyph
