Summary: selecting area in navigator window is off sometimes

Initial Comment:
Show the 'navigator' window
Zoom in 4 or 5 times so only a fraction of the canvas is visible at a time
Resize the navigator window so that it is very wide but not very tall.  The canvas should be scaled down with large blank areas on the left and right.
Click and drag around in the navigator window.  The red rectangle should go wherever the mouse pointer is, but it actually moves much slower than the mouse pointer.

If you resize the navigator window so that it is tall and thin, then the dragging works fine.

I think the problem is in synfig-studio/src/gtkmm/dock_navigator.cpp but haven't been able to fix it yet.

It's something to do with the calculation of xaxis and yaxis both being based off the width of the window, when in fact the whole width isn't always used:

		xaxis = sx * w / (float)canvw;
		yaxis = xaxis/ph;
		xaxis /= pw;
