You should combine a scaling and a translation, e.g.:

General.ScaleX = 5;
General.ScaleY = 5;
General.TranslationX = 1;
General.TranslationY = 0;

You can also specify rotations by using General.RotationX,
General.RotationY and General.RotationZ (if General.Trackball==0) or
General.TrackballQuaternion0, General.TrackballQuaternion1, etc. (if
General.Trackball==1).

The easiest is often to fine-tune the viewport in the GUI using the
mouse, and then use "File->Save As->Gmsh options" (or click on the '?'
button in the graphic window) to save all the parameters.
