/**
|
|
* Frame.createFromGrid accepts grids that are rotated by 90deg from
|
|
* the visual/usual way. (column-based grid)
|
|
*
|
|
* For testing, it's easier for be able to specify a row-based grid, because
|
|
* it visually matches what the image will look like.
|
|
*
|
|
* For instance :
|
|
*
|
|
* [[black, black, black],
|
|
* [white, white, white]]
|
|
*
|
|
* we expect this to be a 3x2 image, one black line above a white line.
|
|
*
|
|
* However Frame.createFromGrid needs the following input to create such an image :
|
|
*
|
|
* [[black, white],
|
|
* [black, white],
|
|
* [black, white]]
|
|
*
|
|
* This helper will build the second array from the first array.
