/**
* pango_matrix_transform_rectangle:
* @matrix: a #PangoMatrix, or %NULL
* @rect: (inout) (allow-none): in/out bounding box in Pango units, or %NULL
*
* First transforms @rect using @matrix, then calculates the bounding box
* of the transformed rectangle. The rectangle should be in Pango units.
*
* This function is useful for example when you want to draw a rotated
* @PangoLayout to an image buffer, and want to know how large the image
* should be and how much you should shift the layout when rendering.
*
* If you have a rectangle in device units (pixels), use
* pango_matrix_transform_pixel_rectangle().
*
* If you have the rectangle in Pango units and want to convert to
* transformed pixel bounding box, it is more accurate to transform it first
* (using this function) and pass the result to pango_extents_to_pixels(),
* first argument, for an inclusive rounded rectangle.
* However, there are valid reasons that you may want to convert
* to pixels first and then transform, for example when the transformed
* coordinates may overflow in Pango units (large matrix translation for
* example).
*
* Since: 1.16
