2) from a drawing of the display in DXF format.
3)
4) See for example "examples/5x2panels8x12.dxf".
5)
6) The layers containing drawing data are:
7)
8) layer "video": one rectangle describing the area of the video frame,
9) representing the outline of the video area of the physical
10) display
11) layer "pixel": one circle (diameter does not matter) for each LED
12) located at the correct position, representing the
13) physical position of the LED in the physical display
14) comment: the two points above mean that the drawing is actually a to-scale
15) mechanical drawing of the real display
16) layer "cable 1": lines connecting the pixel circles in the drawing in the
17) same way as the real wires connect the real LEDs,
18) the lines have to go a bit into each pixel circle,
19) make sure different cable lines do no touch or cross
20) layer "cable 0": another layer for data cables, use this when a cable line
21) crosses a cable line on layer "cable 1"

22) layer "distributor 0": one rectangle describing the first distributor, all
23) cable line to the first pixel of each chain must
24) start in this rectable; the cable lines going out
25) of this rectangle must be in order, i.e. first
26) line leaving is output 0, second one is output 1,
27) and so on; the first four outputs go to the first
28) RJ45 connector, ...; the text in the drawing is
29) ignored (example file contains "000" for the
30) human that is seeing the drawing)
31) layer "distributor 1": second distributor (not in example drawing)
32) layer "distributor 0x2": ...
