I can’t trunc the texture coordinates, because of floating point errors.
Knocking off a pixel from width and height makes sense, I’ll try that out.
Don’t know what you mean by
“build the quads to match exactly what the shader does so that the set
coordinates of the quad is the function that handles the translation.”
Edit: Multiplying texture coordinates by (1 / 1023) instead of (1 / 1024) did not work.
