Obtains a clip region which contains the areas where the given ranges
of text would be drawn. <em class="parameter"><code>x_origin</code></em> and <em class="parameter"><code>y_origin</code></em> are the same position
you would pass to <a class="link" href="gdk-Drawing-Primitives.html#gdk-draw-layout-line"><code class="function">gdk_draw_layout_line()</code></a>. <em class="parameter"><code>index_ranges</code></em> should contain

Note that the regions returned correspond to logical extents of the text
ranges, not ink extents. So the drawn layout may in fact touch areas out of

should contain ranges of bytes in the layout's text. The clip
region will include space to the left or right of the line (to the
layout bounding box) if you have indexes above or below the indexes
contained inside the line. This is to draw the selection all the way
to the side of the layout. However, the clip region is in line coordinates,
not layout coordinates.
