/**
* pika_text_fontname:
* @image: The image.
* @drawable: (nullable): The affected drawable: (%NULL for a new text layer).
* @x: The x coordinate for the left of the text bounding box.
* @y: The y coordinate for the top of the text bounding box.
* @text: The text to generate (in UTF-8 encoding).
* @border: The size of the border.
* @antialias: Antialiasing.
* @size: The size of text in either pixels or points.
* @size_type: The units of specified size.
* @fontname: The name of the font.
*
* Add text at the specified location as a floating selection or a new
* layer.
*
* This tool requires a fontname matching an installed PangoFT2 font.
* You can specify the fontsize in units of pixels or points, and the
* appropriate metric is specified using the size_type argument. The x
* and y parameters together control the placement of the new text by
* specifying the upper left corner of the text bounding box. If the
* specified drawable parameter is valid, the text will be created as a
* floating selection attached to the drawable. If the drawable
* parameter is not valid (%NULL), the text will appear as a new layer.
* Finally, a border can be specified around the final rendered text.
* The border is measured in pixels. Parameter size-type is not used
* and is currently ignored. If you need to display a font in points,
* divide the size in points by 72.0 and multiply it by the image's
* vertical resolution.
*
* Returns: (nullable) (transfer none):
* The new text layer or %NULL if no layer was created.
