get-tabs

Returns the current tab position array as a list.

• (send a-text get-tabs length tab-width in-units) -> list of real numbers
      length = #f : boxed exact non-negative integer or #f
      tab-width = #f : boxed real number or #f
      in-units = #f : boxed boolean or #f

  The length box is filled with the length of the tab array (and therefore the returned list), unless length is #f. The tab-width box is filled with the width used for tabs past the end of the tab array, unless tab-width is #f. The in-units box is filled with #t if the tabs are specified in canvas units or #f if they are specified in space-widths, unless in-units is #f.
