Consider the function
gaddtext(text, window_coord, text_coord)

window_coord refers to the plotted area in relative coordinates [x, y]
where x and y vary from zero to one.

Is there any way to query O-matrix as to the min and max coordinate
values in x and y, so that plotted values can be converted to the
needed relative coordinates?

There could be alternate answers, really, such as a way to query the
axis limits, or a function to do the whole conversion.

Obviously in many cases it is possible to know what the axis limits
will be, or to set them, but it is more general if I can query to find
out.

Thank you.
