animated floodfill

[unitycoder]

some ideas to make floodfill appear slowly:

convert
void FloodFill(int x, int y
into coroutine
IEnumerator FloodFill(int x, int y

then add yield return null; inside the while loop.
(could make it being called only every x steps though, to keep it faster)

also need to call the floodfill with StartCoroutine() then.
AND might have to set textureNeedsUpdate to true from the coroutine loop also.
