Feature Request: Pre-Blur the image before the shader is processed to soften aliasing #71

I just wanted to say thank you, I've been looking for something like this for ages after discovering shaders in RetroArch, and this is exactly that! It works fantastic, and so far haven't found any major bugs.

However, aesthetically, I was wondering if it were possible to add an option under Input to add a bit of a blur to the source input before the shader is processed. Some shaders already do this, but others do not. I was using it to watch some movies and TV shows, and once I got it dialed in to roughly what a 480p output would look like with the scanlines the size that looks right... I still saw chunky stair stepping aliasing on diagonal lines that were distracting and not quite how they are represented on my old crt. With just a bit of pre-blur that would soften that up without anything complicated. I tried multiple if not all the shaders to find a way to get around it, but wasn't able to find something that had quite the look I was going for

Perhaps with a .5, 1 pixel, 2 pixel, etc set of options perhaps

I just wanted to say again, Thank You! This is great and I love it.
