At first glance from the code sample alone you may assume that pixel XY to texel UV would be achieved by by normalizing to 0-1 range:

float u = x / (texture.width - 1);  
float v = x / (texture.height - 1);

However as the documentation above says this is not correct, you should instead normalize to one pixel less, as a UV of 1 is would be the same as 0 in repeat filter mode, so instead the conversion should be:

float u = x / texture.width;  
float v = x / texture.height;
