.scad model not preserve dimensions

[shalnoff]

the resulted .scad has wrong dimensions. Obvious recommended workaround is to use scale() to restore the target size. Nevertheless, this approach has considerable disadvantage, since "traditional transforms (translate, rotate, scale, mirror & multimatrix) are performed using OpenGL in preview, while other more advanced transforms, such as resize, perform a CGAL operation, behaving like a CSG operation affecting the underlying object, not just transforming it." (proof)

In complex models it cause preview defects, that significantly complicate the process of construction.

Making the export of scad model in 1:1 scale most probably could eliminate this and possible other related problems.
