About how PCSX2 stores images in memory

[Blyss Sarania]

Move pixels... hmm... nope, but you can sample from another position. For example:

vec2 pos; // current position
vec3 color; // color output

// pass through, no changes.
color = sampler(texture, pos);

So you cannot move pixels, but you can do something like this:

if(pos.x > section4) pos.x += 6.0;
else if(pos.x > section3) pos.x += 4.0;
else if(pos.x > section2) pos.x += 2.0;

// no longer pass through, as it will sample from a different position.
color = sampler(texture, pos);

I think if I'm reading that right, that's what I meant by "move pixels." Read it from one x,y, and write it to another. I will look into this later.
