Font from bitmap

[andrey-zakharov]

I have tileset (bitmap) of chars. I do not see the way to make a font from it. The only what i want is to provide assetPath, and valid chars as char association map with tile index (or even more precise - exact region in bitmap for not-monospaced fonts) in it. Looks like Font currently draw this tileset for itself internally, and i want to provide this tileset by asset.
