Just to let you know that I have found out the reason for this 'failing 
to mirror' problem.
[Unmirrored, the object was visible in the output .PNG file, mirorred, 
it was not.]
The line width I was using is too small (0.001 mm), increasing the width 
to 0.01mm has fixed the problem. I imagine it is due to some rounding 
problem in the maths that mirrors the X-axis:

mainProject->file[5]->transform.scaleX = -1.0;
