Feature Request: Improve Asspect Ratio shader

[FuxorLuck]

Hello

I was recently working on hack for pcsx2 that works for most games this hack do 2 things:

1. Force native video resolution to be 640x512P in order to get higher native rendring resolution
   and progressive rendring
2. Sync reshade depth effects with pcsx2 image when using upscale

Reshade depth effect whitout my hack https://ibb.co/9ZwtLyd
Game with my hack https://ibb.co/zSsszf1

as you can see they are now matcing with each other

also

Like i said my hack also increased the video quality

512x224p: https://ibb.co/MBspYnw
640x512p: https://ibb.co/WKksxbX

The problem is as you can see is that the image doesn't fill the screen

It can be resolved by 2 dieffrent ways:

1. hack the game in order to change frame buffer size
   which I need to make for each game and some games hve changing address for buffer size so it will take a lot of time to acheive just for a single game.
2. make a shader file that strech the image for me, and that is the reason i am asking for your help

I need to strech it down and right

Asspect ratio only allows me to sterch the image Up and down together or left and right together

So if you can help me i will be very grateful
