flood fill ?

[madscijr]

I think it would be ideal to add a parameter like EnableBlend% to the fill function, where if _TRUE, do the fancy alpha blend stuff, else do it simpler & quicker. 

Most immediately I wanted a fill for one of those color wheel screensaver animations, so will want speed before alpha, but I think the alpha will come in handy for other projects.

Thanks for all your help and code with this!
