* A few hints on how the positioning of the text frame is done:
*
* Let's assume we have a bar chart, a text for a positive value
* to be drawn, and "North" as attrs.positivePosition().
*
* The reference point (pos) is then set to the top center point
* of a bar. The offset now depends on the alignment:
*
* Top: text is centered horizontally to the bar, bottom of
* text frame starts at top of bar
*
* Bottom: text is centered horizontally to the bar, top of
* text frame starts at top of bar
*
* Center: text is centered horizontally to the bar, center
* line of text frame is same as top of bar
*
* TopLeft: right edge of text frame is horizontal center of
* bar, bottom of text frame is top of bar.
*
* ...
*
* Positive and negative value labels are treated equally, "North"
* also refers to the top of a negative bar, and *not* to the bottom.
*
*
* "NorthEast" likewise refers to the top right edge of the bar,
* "NorthWest" to the top left edge of the bar, and so on.
*
* In other words, attrs.positivePosition() always refers to a
* position of the *bar*, and relPos.alignment() always refers
* to an alignment of the text frame relative to this position.
