You can get the result you want by either-
 1) using gopen with MODEL_XFORM
or
 2) repeating "push_matrix3d(fd, left_to_right);" after view_matrix3d

If you are not in MODEL_XFORM mode, then view_matrix3d will pop off all
of the transforms on the current transform matrix stack, since they all
have the old view matrix concatenated into them.  In MODEL_XFORM mode
the modelling transforms are kept separate and do not need to be flushed.
