Vexel is raster. Vector is well, vector. I know what I speak of.

Vector uses vector layers. Yes you have to rasterize for the final output but with using the vector layers, you can resize indefinitely without losing quality. I use Illustrator to create my stuff and because its sheer vector, I can resize my final image however I like and then send it to photoshop for the output. And the best thing is it does not lose quality.

Also, vector layers are extremely editable, especially in Illustrator, in contrast to raster, which are not. So yes, in a sense, it does matter what program he used but not that important, not as important as what format of layering he used. If he used raster, IT IS NOT VECTOR! ITS VEXEL. If it did not matter, they might as well take out the classifications on DA to specify. I do agree with you on the point it ultimately becomes raster in the end.

And I did CnC. Not too sure if this comment was mainly directed at me. Also, in order to burn the areas, it needs to be in raster form, A.K.A making it vexel! =]
