Context.setBaseDir

Sets the base direction for the context.

The base direction is used in applying the Unicode bidirectional algorithm; if the direction is [pango.types.Direction.Ltr] or [pango.types.Direction.Rtl], then the value will be used as the paragraph direction in the Unicode bidirectional algorithm. A value of [pango.types.Direction.WeakLtr] or [pango.types.Direction.WeakRtl] is used only for paragraphs that do not contain any strong characters themselves.
