draggable axis line limits

[Ichibot200]

Perhaps there should be possibility to keep the draggable line within plot area? Right now if I drag a line out of plot area, I can never access it again - that is of course if I have defined my axis region manually and is rendered every iteration in such area.

Maybe defining V or H lines like:

public void PlotVLine(double x, Color? color = null, double lineWidth = 1, string label = null, bool draggable = false, bool bounds = false, double xMin = 0, double xMax = 50)

This is a good idea. I'll put this in shortly.

I'll probably add arguments so you can call it like like:

plt.PlotVLine(123, draggable: true, dragLimitLower: 0, dragLimitUpper: 1000);

And those limits will default to - and + infinity if not specified.

I added 2 extra arguments to let you limit how far the user can drag a draggable axis line. 6af45af

scottPlotUC1.plt.PlotVLine(position, draggable: true, dragLimitLower: 0, dragLimitUpper: 49);

By default those arguments are negative and positive infinity (no restriction on dragging).

I'll publish this with the next NuGet release
