Tracing through the C sources of gtk+, GtkVScrollBar inherits size- 
allocate all the way from GtkRange, which calls gtk_range_calc_size 
(), which calls gtk_range_get_props(), which calls  
gtk_widget_style_get() to ask the theme engine for various  
dimensional properties of the widget.

  "slider-width"
  "trough-border"
  "stepper-size"
  "stepper-spacing"
  "arrow-displacement-x"
  "arrow-displacement-y"


So, the width/height of a vertical/horizontal scrollbar is, indeed,  
controlled by the theme, or at least by user RC files.  This sort of  
thing should not be controlled by application code.
