did a quick search of the forums this morning and didnt find an answer so i'll ask....
how does NGUI determine the size (or scale) of a sprite (sliced or otherwise) when adding to a scene...NGUI never seems to set the scale of a sprite equal to what the original size is...i.e. if i have a sprite that is 64x64, after adding it to a scene, the scale might be 100x100, or might be smaller as well...clicking on "make pixel perfect" doesnt seem to affect anything.
