Flood Fill optimization for IL2CPP

[muhammadtahir08]

Actually flood fill works fine until you are working with mono scripting back-end when you switch to IL2CPP then flood fill makes the app very slow so i think there will be a way to optimize this algorithm.
i am using FloodFillMaskOnlyWithThreshold

does profiler show what makes it slower in il2cpp?

but i'd suggest trying to do the pixel collecting part in another thread,
and using something better than queue:
#41

I have tried both Scripting back-end IL2CPP and Mono Scripting back-end when i use mono scripting back-end it works fine on the other hand when i switch to IL2CPP totally negative results.
i also attached screenshot while i was observing on mobile its shows that mobile paint flood takes almost 5k+ cpu clock cycle to execute it. the screenshot taken i used the flood fill. Queue having BigofO(1) for insertion and deletion. so i think main problem is that what happen when we convert it to IL2CPP, while it works fine on Mono scripting back-end.
