[BUG] VRML export options ref_x and ref_y doesn't work as expected

[rainer38]

Describe the bug
The options "ref_x" and "ref_y" of output type "vrml" doesn't work as expected.
The option "ref_y" has no effect at all.
The option "ref_x" always shift in x and y direction the same amount of units.

I compared the VRML files and it shows the coordinate offset for ref_y is ignored and for ref_x is applied to x and y coordinates

To Reproduce
I use the following yaml configuration:

kibot:
  version: 1

global:
  dir: /mnt/ramdisk/test/
  units: millimeters

outputs:
- name: export_vrml
  comment: PCB to VRML export
  type: vrml
  options:
    output: '%f_v%br_%I.%x'
    download: false
    dir_models: ''
    use_pcb_center_as_ref: false
    ref_x: 110.0
    ref_y: 90.0

The problem is reproducible with every KiCAD board, no special requirements.
After i import the VRML file in Blender or FreeCAD the placement of the objects are not correct.

Expected behavior
When i use ref_x=110 and ref_y=90 i expect the board to be shifted 110 units in x direction and 90 units in y direction within the VRML file.

Screenshots
In the KiCAD pcb the lower left corner of the Edge.Cut Layer is at 110,90.
When i set ref_x=0 and ref_y=0 the lower left corner of the imported pcb is at the expected position (110,-90)

When i set ref_x=0 and ref_y=90 the lower left corner of the imported pcb is still at the position (110,-90) which is wrong.

When i set ref_x=110 and ref_y=0 the lower left corner of the imported pcb is at the position (0,20) which is wrong.

When i set ref_x=110 and ref_y=90 the lower left corner of the imported pcb is at the position (0,20) which is wrong.

The difference between the options refx=0, ref_y=0 and ref_x=110, ref_y=0 is an offset of exact 110 in x and y direction.

Environment (please complete the following information):
I use the deb packages on Debian bullseye and manually run kibot on the command-line.

Thanks for the detailed explanation.

The code was incomplete. Now should work.

Now the coordinates are where they should be. Nice work.
