New Post: DrawingLayers vs Manual Graphics Creation

I had been creating temporary symbology (such as GPS points) manually using some ideas I discovered here:

https://dotspatial.codeplex.com/discussions/349648

I then discovered 'DrawingLayers' I was curious if there is any reason to continue generating symbols manually or if I can switch over to using the DrawingLayers. Is there any sort of performance trade off? Or perhaps I am not fully understanding the use case of the 'Drawing Layers'?

thanks,

also i noticed some patches i submitted have disappeared since the switch to Git, should I resubmit them as pull requests?
