Profile start and end point no longer working in v0.17.1

[GoogleCodeExporter]

A file created in v 0.15 with specified start and end points for the profile 
operation doesn't work in 0.17.1.

The generated python code is different in the following way:

Code out of 0.17.1:
kurve_funcs.make_smaller( curve, start = area.Point(0.37, -0.08), finish = 
area.Point(0.36, -0.07))
roll_on = 'auto'
roll_off = 'auto'
kurve_funcs.clear_tags()
kurve_funcs.add_tag(area.Point(-0.07, 3.28), 0, 0.7853981634, 0.2)
kurve_funcs.add_tag(area.Point(-0.1, 1.51), 0, 0.7853981634, 0.2)
kurve_funcs.add_tag(area.Point(5.59, 1.37), 0, 0.7853981634, 0.2)
kurve_funcs.add_tag(area.Point(5.57, 3.4), 0, 0.7853981634, 0.2)
kurve_funcs.profile(curve, 'right', tool_diameter/2, offset_extra, roll_radius, 
roll_on, roll_off, rapid_down_to_height, clearance, start_depth, step_down, 
final_depth)

Working code out of v0.15 (ish)
kurve_funcs.make_smaller( k10, startx = 0.37, starty = -0.08, finishx = 0.36, 
finishy = -0.07)
roll_on = 'auto'
roll_off = 'auto'
kurve_funcs.clear_tags()
kurve_funcs.add_tag(-0.07, 3.28, 0, 0.7853981634, 0.2)
kurve_funcs.add_tag(-0.1, 1.51, 0, 0.7853981634, 0.2)
kurve_funcs.add_tag(5.59, 1.37, 0, 0.7853981634, 0.2)
kurve_funcs.add_tag(5.57, 3.4, 0, 0.7853981634, 0.2)
kurve_funcs.profile(k10, 'right', tool_diameter/2, offset_extra, roll_radius, 
roll_on, roll_off, rapid_down_to_height, clearance, start_depth, step_down, 
final_depth)

I created a sample file (inch units) showing the problem.  It looks like it 
might be something in how the python kurve_funcs is called or in that library 
code, since if I try to make the python script look like the old call, that 
doesn't work either...

I have repeated this problem. In kurve_funcs.py, in make_smaller, 
curve.ChangeStart and curve.ChangeEnd were expecting a point exactly on the 
curve. I have fixed this by changing the python code to this 
"curve.ChangeStart(curve.NearestPoint(start))".
Also, curve.ChangeEnd wasn't working correctly. I have fixed this in the "area" 
module.

It looks like the end point works again now, but the start point still seems to 
have a problem.  It looks like it's not finding the nearest point on the curve 
for the start.  It seems to find the nearest vertex to my rectangle to start.  
See attached file.
