I did asume a value for height to width relation but itis more like a zoom factor.

I saw in the code both are using the x,y,w,h / MAIN_Scale and then
calling the not Scaled function.

CWidget.cpp:
BEGIN_METHOD(CWIDGET_resize_scaled, GB_FLOAT w; GB_FLOAT h)

  int w, h;

  w = (int)(VARG(w) * MAIN_scale);
  h = (int)(VARG(h) * MAIN_scale);

  resize_widget(_object, w , h);

END_METHOD

Here it act as a zoom factor instead screen width/height relation.

?? if in the CWidget.cpp the MAIN_scale equals 1 the valuas for x,y,w, and h
stay the same.

As you say above "But it isn't finished." we wait till it is :)
