rectangle used to store the extents of the layout as drawn or NULL to indicate that the result is not needed. out[allow-none]
rectangle used to store the logical extents of the layout or NULL to indicate that the result is not needed. out[allow-none]
Computes the logical and ink extents of layout in device units. This function just calls pango_layout_get_extents() followed by two pango_extents_to_pixels() calls, rounding ink_rect and logical_rect such that the rounded rectangles fully contain the unrounded one (that is, passes them as first argument to pango_extents_to_pixels()).
