FloodFillFX Crash

[Nejuf]

If the image's height is not divisible by the offset, this results in a crash because a script timeout. The reason being that subtracting the offset from a uint(dropY), can cause it to be negative, but since uint's can't be negative, the result is a very large number.

A simple restructuring in the draw() method fixes the problem.

Changing:

dropY -= offset;

dropRect.y -= offset;

if (dropY <= 0)
{
complete = true;
}

Into:

if (dropY <= offset)
{
    dropY = 0;
    complete = true;
}
else
{
    dropY -= offset;
    dropRect.y -= offset;
}
