The function creates a line annotation. The simplest form of a line annotation represents a simple
straight line that has an associated PopUp annotation to display the string Content in a floating
window.
The initial window state of the associated PopUp annotation is closed by default but the state can be
changed with SetAnnotOpenState() if necessary.
The coordinates are interpreted in current user space. Any transformation that was applied on the
coordinate system will be taken into account.
The parameter FillColor is only used if the line end style of the start or end point has an interior that
can be filled. The special constant NO_COLOR represents a transparent interior.
The stroke color is required and must not be set to NO_COLOR.
Measure lines
A measure line is an extended line annotation that has additional properties. To create a measure
line create first the line annotation and set then the measure line specific properties with
SetLineAnnotParms().
