◆ appendTriangle() [1/2]

void QSGCurveStrokeNode::appendTriangle	(	const std::array< QVector2D, 3 > &	vtx,
		const std::array< QVector2D, 2 > &	ctl,
		const std::array< QVector2D, 3 > &	normal,
		const std::array< float, 3 > &	extrusions = defaultExtrusions() )

Append a triangle with vtx corners within which the fragment shader will draw the visible part of a line from ctl[0] to ctl[2].

The normal vectors are used in the vertex shader to expand the triangle according to its stroke width: therefore, it's ok for the triangle to be degenerate, and get expanded to size in the vertex shader. Normals are usually unit vectors, but it's also ok for some to have larger magnitudes, to handle the case when miter corners need to be extended proportionally farther as stroke width increases.
