                 Summary: fltk shows wrong coordinates of the mouse cursor

Details:

When I do


octave:1> version 
ans = 3.4.0
octave:2> graphics_toolkit ('fltk')
octave:3> x=0:0.05:2*pi ; y=sin(x); plot(x,y)
octave:4> 


the sine plots correctly, but the mouse cursor is off: it shows for instance
that 'y'=0.994 when it is clearly above 1.

The screenshot shows the 'miscalculation'. Due to the screenshot, the 'cross'
cursor has turned into a 'arrow' cursor, but I found this (tiny) bug using the
cross-cursor.

The relative error seems to persist for bigger numbers too.

Octave+Gnuplot does it correctly.
