GtkLabel: angle and ellipsize are incompatible?

[Yu Feng <rainwoodman gmail com>]

Dear List,

I noticed this line in gtklabel.c:

gtk_label_ensure_layout:
...
      if (angle != 0.0 && !label->wrap && !label->ellipsize && !
label->select_info)
    {  
      /* We rotate the standard singleton PangoContext for the widget,
       * depending on the fact that it's meant pretty much exclusively
       * for our use.
       */
...

Why is ellipsize incompatible with angle? There at least won't be any
problems when the angle is 90, 180, 270, will there?

Regards,

Yu
