## Description

GtkSourceMap is a widget that maps the content of a GtkSourceView into a smaller view so the user can have a quick overview of the whole document.

This works by connecting a GtkSourceView to to the GtkSourceMap using the “view” property or `gtk_source_map_set_view()`.

GtkSourceMap is a GtkSourceView object. This means that you can add a GtkSourceGutterRenderer to a gutter in the same way you would for a GtkSourceView. One example might be a GtkSourceGutterRenderer that shows which lines have changed in the document.

Additionally, it is desirable to match the font of the GtkSourceMap and the GtkSourceView used for editing. Therefore, “font-desc” should be used to set the target font. You will need to adjust this to the desired font size for the map. A 1pt font generally seems to be an appropriate font size. "Monospace 1" is the default. See `pango_font_description_set_size()` for how to alter the size of an existing PangoFontDescription.
