How to Make Blurry Rectangles with surface.Draw(Textured)Rect?

[Paperclippy]

Hello, I'm wanting to make a rectangle blurry, but I don't know how. There are a bunch of things that say "blur," but I don't know how to use them correctly. All I want is a blurry transparent rectangle coloured black, and I'm trying to use surface.DrawRect or surface.DrawTexturedRect, which one do I use for a blur effect, and what do I do? I've tried searching the internet for this, but it's just something stupid, so I guess nobody has any tutorials... So if you know, I'd like at least an example of a blurred rectangle/texture and the code so that maybe I can learn from that. Thank you :D

Do you mean you want the background behind the rectangle to be blurred? [URL="https://github.com/Facepunch/garrysmod/blob/master/garrysmod/lua/derma/derma_utils.lua#L7-L34"]If so, you just need to draw a couple of textured rects with a blur material.[/URL]

Or, do you mean you want the edges of the rectangle to be blurred?
