Data Fields
int16_t	x0
	End-point 0 X in pixels.
int16_t	y0
	End-point 0 Y in pixels.
int16_t	x1
	End-point 1 X in pixels.
int16_t	y1
	End-point 1 Y in pixels.
uint16_t	width_px
	Stroke width in pixels.

	0xAARRGGBB stroke colour.

Detailed Description

Anti-aliased line parameters.

Two end-points and a stroke width. HUM Ch 62.4.4 "Lines" p 3725 documents the 6-limiter encoding the engine uses internally; this driver pre-computes those limiters from (x0,y0,x1,y1,width).
