/Text2DS displays a text (string) directly
on the two-dimensional space on screen.
No corresponding classes exist in GEANT4.
Note that its position, i.e., left end of the string,
is described with 2D position vector described
in units of ``mm'',
and its origin is the left bottom of the screen.
Font size should be given in units of ``pt''.
/Text2DS is convenient to add title strings etc
to drawn figures afterwards.
| Format | /Text2DS x_mm y_mm size_pt string |

For example, the following lines described in the modeling block
displays a large title "Supported Primitives 1" at the bottom center of
the screen:
### black color /ColorRGB 0 0 0 ### font name /FontName Times-Roman ### 40-pixel string at (30, 40) on screen /Text2DS 30 40 40 Supported Primitives 1
