Please see the updated

Remapping coordinates (pixels within panels and assigning pixel order across panels)
------------------------------------------------------------------------------------
Some panels do not even output pixels in the natural left to right, up to down order.
For those, see multipler lower down on this page.

For now, let's focus on how panels are chained. 
You might choose a different physical layout than the wiring provides.
The library by default will do this the horizontal way
```
chain 1 - P1 - P2 - P3
chain 2 - P1 - P2 - P3
chain 3 - P1 - P2 - P3
```

Once you go past 4 or 5 panels wide, you may want to have a layout like this.
For that, you want U-mapper.
```
chain 1 - P1 - P2 - P3
          P6 - P5 - P4
chain 2 - P1 - P2 - P3

I wrote this to show how to handle a 52 panel display wired this way
