uint16_t	y
	First lead tile row.
uint16_t	step_x
	Per-tile column delta (0 or 1).

	Tiles on the lead edge (pre-budget).

Detailed Description

The lead-edge tile run a pan prefetch walks (one row or one column).

(x, y) is the first tile; each successive tile steps by (step_x, step_y) (one of them 1, the other 0); count tiles lie on the run before the tile-grid clamp / budget cap are applied.
