Virtual panel 1x4

[aidarishkulov]

I launch by placing 4 panels on top of each other. Connection from bottom left to top.
In the first lower module, the x coordinates are the same, and in the 3 upper ones they are shifted by one pixel. In the 2nd and 4th panels, x is shifted to the left, and in the 3rd panel to the right by one pixel.
The у coordinates are the same.
Controller HD-WF2.
64x32 panels, FM6124 driver.

I had to look here, now it's normal. #134 (comment)

Another problem was found: the color shades of modules 1 and 3 are different from 2 and 4 in the example above. The panels are normal, when swapped, the shades remain the same. White turns bluish.
