I am using the Oldschool Pixel Shader for my current project. I want to make a 64x64 pixel window, but allow it to be bigger on screen.

So I set the window to 640 x 640, then apply the Oldschool Pixel Shader at 64 x 64.

It works, and each "pixel" is 10 x 10 actual pixels. however it seems to start halfway through a "pixel," so the first "pixel" in each column or row is only 5 x 5 or 5 x 10 pixels.



Is there any way to remove this offset so the full pixel begins in the corner?
