+/* Text item for the canvas. Text items are positioned by an anchor point and an anchor direction.
+ *
+ * A clipping rectangle may be specified for the text. The rectangle is anchored at the text's anchor
+ * point, and is specified by clipping width and height parameters. If the clipping rectangle is
+ * enabled, it will clip the text.
+ *
+ * In addition, x and y offset values may be specified. These specify an offset from the anchor
+ * position. If used in conjunction with the clipping rectangle, these could be used to implement
+ * simple scrolling of the text within the clipping rectangle.
+ *
+ * The following object arguments are available:
+ *
+ * name type read/write description
+ * ------------------------------------------------------------------------------------------
+ * text string RW The string of the text label
+ * x double RW X coordinate of anchor point
+ * y double RW Y coordinate of anchor point
+ * font string W X logical font descriptor
+ * fontset string W X logical fontset descriptor
+ * font_gdk GdkFont* RW Pointer to a GdkFont
+ * anchor GtkAnchorType RW Anchor side for the text
+ * justification GtkJustification RW Justification for multiline text
+ * fill_color string W X color specification for text
+ * fill_color_gdk GdkColor* RW Pointer to an allocated GdkColor
+ * fill_stipple GdkBitmap* RW Stipple pattern for filling the text
+ * clip_width double RW Width of clip rectangle
+ * clip_height double RW Height of clip rectangle
+ * clip boolean RW Use clipping rectangle?
+ * x_offset double RW Horizontal offset distance from anchor position
+ * y_offset double RW Vertical offset distance from anchor position
+ * text_width double R Used to query the width of the rendered text
+ * text_height double R Used to query the rendered height of the text
+ *
+ * These are ignored in the AA version:
+ * use_ellipsis boolean RW Whether to use ellipsises if text gets cut off. Meaningless if clip == false.
+ * ellipsis string RW The characters to use as ellipsis. NULL = "...".
