NeoTiles object

The NeoTiles object is constructed with two layout "methods" that provide the mapping from the 2d coordinate system to a index that the NeoPixelBus requires.

template <typename T_MATRIX_LAYOUT, typename T_TILE_LAYOUT> class NeoTiles

The T_MATRIX_LAYOUT will define how the pixels on an individual matrix panel are laid out.
The T_TILE_LAYOUT will define how the matrix panels are laid out in the bigger tile arrangement.
See Layout objects for all the possible "methods".

This object has the restriction that all the panels within the collections use the same layout and the same orientation. The NeoMosaic object will rotate the panels to shorten the interconnection distance between panels.

Once you have constructed one, you can then use it map a given x,y to a index and then use this to set a pixel color.

NeoPixelBus<NeoGrbFeature, Neo800KbpsMethod> strip(PixelCount, PixelPin);
NeoTiles <RowMajorAlternatingLayout, ColumnMajorAlternatingLayout> tiles(
    PanelWidth,
    PanelHeight,
    TileWidth,
    TileHeight);

...
strip.SetPixelColor(tiles.Map(4, 5), RgbColor(16,16,98));

Using the NeoPixelsTilesDump.ino sample, the following are some example layouts.
