title: QuickFill/flood fill algorithm
body: <p>I need a flood fill algorithm to fill existing raster shapes with various colors and fill patterns. From what I know, the QuickFill algorithm is the best way to do a flood fill. I've found a number of implementations, but they are all in C++ and use Windows SDK functions. The problem is that I need a .NET implementation.</p>
  <p>If worse comes to worse I can write a new implementation, but I would rather use an existing implementation (that hopefully doesn't have bugs). Is anyone aware of an existing flood fill implementation in C#/VB.NET?</p>
