In case that wasn't clear, what I mean is this:

Before, the issue of normalization and sampling were separate.  If people included a pixel convolution, they were integrating within pixels and then sampling, whereas if they did not, they were just sampling at pixel centers.  When doing the latter you had issues like the total flux not adding up to the object flux, etc.  Then there was an additional option (normalization) related to whether what was being drawn had the pixel area factor included, or not.
