This interface provides methods to manage a crosshairs control.

The crosshairs control, which has a programmatic identifier equal to APC_Crosshair, works like an x-y graph. Both x and y lines can be adjusted separately. There is a maximum and minimum x- and y-coordinate and the position of the cross hair is specified by two values that fall in this range.
The target box stays inside the bounding rectangle at the extremes. This means that four pixels must be added to the height and width. To calculate the target box, use the following equations:
Height = 4 + (<number of vertical steps> * <pixels per step>)
Width = 4 + (<number of horizontal steps> * <pixels per step>)
The IASCrossHair interface, which has a global unique identifier (GUID) equal to IID_ASCROSSHAIRS, inherits from IASControl.
