Meshviewer mesh output reversed per line after reboot

[ThomasToka]

Describe the bug The mesh is reversed on loadup via RTS_INIT

To Reproduce Steps to reproduce the behavior:

1. generate mesh
2. look at the lines.. for example 1 2 3 4 5
3. reboot printer
4. go to meshviewer, each line is reversed so the example line gets 5 4 3 2 1

Expected behavior showing as saved

Additional context the fix for this is to change the order here:

  // away from origin
  if (zig)
  {
    inStart = GRID_MAX_POINTS_X - 1;
    inStop = -1;
    inInc = -1;
  }
  else
  {
    // towards origin
    inStart = 0;
    inStop = GRID_MAX_POINTS_X;
    inInc = 1;
  }

Thank you for the code. I included it in my fork and came to this bug after user reports.
