[GRASS-dev] d.vect render= and corrupted vector display

[Maciej Sieczka]

Hi

I have tried different render methods with a vector box which fits the
region perfectly. For each render method the vector box is displayed
wrong on the X mointor. Details:

in spearfish:

$ g.region rast=elevation.10m -a
$ v.in.region output=frame type=line
$ d.mon x0

#1
$ d.vect frame rander=g
(right egde of the vector box invisible)

#2
$ d.erase; d.vect frame render=r
(right egde of the vector box invisible)

#3
$ d.erase; d.vect frame render=d
(right egde of the vector box invisible)

#4
$ d.erase; d.vect frame render=c
(nothing is visible)

#5
$ d.erase; d.vect frame render=c
(nothing is visible)

Then I repeated tests with width=2 and greater.

For cases 1-3 the right edge became visible, but the right and left
edges were thinner than top and bottom.

For case 4, no matter what width nothing is visible.

For case 5, width > 1 makes the right edge visible, but the other 3 are
 never displayed.
