The X-axis scroll position of child map in a container viewport.

The value is in map units. These co-ordinates are floating-point numbers, and use the same relative co-ordinates as $Xpos and $Ypos.

For $MapScrollX, position '0' is when the scroll bar is in the middle of the view's vertical window scroller.

In the parent's viewport $MapScrollX is drawn halfway across the interior of the container's icon (i.e. $Width/2) though depending on $TitleHeight the position itself may be obscured.

If $MapScrollX/Y are {0,0}, then a note where $Xpos=0;$Ypos=0 will be around the middle of the screen.

This attribute works in conjunction with $MapScrollY.

The attribute can be set via actions so it is possible to pre-set a particular area of the parent map to be set to be onscreen when opened.
