Remove some unused gnome-canvas options.

Simplifies the drawing code a bit.

Public API removed:

  GnomeCanvas.center_scroll_region  (is always TRUE)
  GnomeCanvas.pixels_per_unit       (is always 1.0)

  gnome_canvas_set_center_scroll_region()
  gnome_canvas_get_center_scroll_region()
  gnome_canvas_set_pixels_per_unit()
