Creating a `PangoLayout` object is the first step in rendering text,
and requires getting a handle to a `PangoContext`. For GTK programs,
youll usually want to use `gtk_widget_get_pango_context()`, or
`gtk_widget_create_pango_layout()`. Once you have a `PangoLayout`,
youll usually want to use [method@Gtk.Widget.get_pango_context], or
[method@Gtk.Widget.create_pango_layout]. Once you have a `PangoLayout`,
you can set the text and attributes of it with Pango functions like
`pango_layout_set_text()` and get its size with `pango_layout_get_size()`.
[method@Pango.Layout.set_text] and get its size with
[method@Pango.Layout.get_size].
*Note*: Pango uses a fixed point system internally, so converting
between Pango units and pixels using `PANGO_SCALE` or the `PANGO_PIXELS()`
macro.
Rendering a Pango layout is done most simply with `pango_cairo_show_layout()`;
you can also draw pieces of the layout with `pango_cairo_show_layout_line()`.
Rendering a Pango layout is done most simply with [func@PangoCairo.show_layout];
