#3320: d.text does not show anything with screen position in geographic
coordinates or pixels

 Reporter:  wenzeslaus      |      Owner:  grass-dev@…
     Type:  defect          |     Status:  new
 Priority:  normal          |  Milestone:  7.2.1
Component:  Display         |    Version:  7.2.0
 Keywords:  d.text d.graph  |        CPU:  Unspecified
 Platform:  Unspecified     |
----------------------------+-------------------------
 G7:d.text works only with the default settings. I get nothing when using
 the `-g` (map/geo coordinates) or `-p` (screen pixels). Same in trunk and
 7.2 (likely also 7.0).

 Relevant flags and option:

 {{{
   -p   Screen position in pixels ([0,0] is top left)
   -g   Screen position in geographic coordinates
   at   Screen position at which text will begin to be drawn (percentage,
 [0,0] is lower left)
 }}}

 How to reproduce:

 {{{
 #!bash
 d.mon wx0
 # OK
 d.text at=50,50 text=TestPer
 # nothing
 d.text at=635334.375,220456.25 -g text=TestCoor
 # nothing
 d.text at=200,200 -p text=TestPx
 # d.mon stop=wx0
 }}}

 Workaround with G7:d.graph:

 {{{
 #!bash
 d.graph -m << EOF
   color black
   move 635334.375,220456.25
   text TestGraph
 EOF
 }}}

 Here is the initialization code in `d.text` and in `d.graph`:

 {{{
 #!c
 /* d.text */
 D_setup_unity(0);

 /* d.graph */
 if (mapcoords->answer) {
     mapunits = TRUE;
     D_setup(0);
 }
 else {
     D_setup2(0, 0, 100, 0, 0, 100);
     mapunits = FALSE;
 }
 }}}
