set-scrollbars

Adjusts the canvas's vertical and/or horizontal scrollbars. Horizontal/vertical scrollbars can only be used in a canvas that was created with the wx:const-hscroll/wx:const-vscroll style flag.

• (send a-wx:media-canvas set-scrollbars horiz-pixels vert-pixels x-length y-length x-page y-page x-value y-value set-virtual-size?) -> void
      horiz-pixels : small integer
      vert-pixels : small integer
      x-length : small integer
      y-length : small integer
      x-page : small integer
      y-page : small integer
      x-value = 0 : small integer
      y-value = 0 : small integer
      set-virtual-size? = #f : boolean

  Does nothing, since the scorllbars are managed automatically.
