New Shader pack: Blur and Glow Shaders!

I've been inspired and over the past week, I've coded a few new shaders which are finally done! 

It took a bit of thinking but I've written shaders that can blur or apply a glowing effect on either a single object or an entire surface in GameMaker Studio 2. They're highly customizable, hopefully having every possible variable you'd need to create any kind of blurring or glowing effect you're thinking of. 

To be honest, this release wasn't my end goal, but until I figure out how to use the depth buffer recently introduced in GMS2, this will have to do.

Give the demo a go and if you liked it, perhaps you'll want to use it in your own projects. It should be easier to use than the Mode7 shader at least.
