text Offset
The default textOffset for all annotations added to this annotation manager if not overwritten by individual annotation settings.
Offset distance of text from its anchor. Positive values indicate right and down, while negative values indicate left and up. If used with text-variable-anchor, input values will be taken as absolute values. Offsets along the x- and y-axis will be applied automatically based on the anchor position. The unit of textOffset is in ems.
