For every justification but baseline-left (and aligned/fit) the DXF
Reference makes group 11 the point the text is placed by; group 10 is a
computed point on the baseline. Left-justified text with a vertical
alignment was drawn, measured and picked from group 10 and then shifted
by the alignment again: TL and ML too low, BL too high. The renderer
(fonts::place) and text extents (doc text_box, used for picking) now
place it from the alignment point; a mirrored (extrusion 0,0,-1) TL/ML/BL
text keeps its alignment point when it turns right-justified; and the
Properties position moves justified text by its alignment point.
