icon_map3.dds X,Y origin

[tknarr]

I've been trying to create a set of icons for the icon_map3 file. I've got it 95% there, but I need a quick check of something.

First, is the origin used in the skinnable_Skinnnable_Styles.xml file for the icons based at 0,0 or 1,1? That is, is 1,1 the upper-leftmost pixel in the .dds image, or is it one pixel down and to the right? Secondly, am I right in calculating that the image chunks extracted are 41 pixels by 41 pixels square with a 1-pixel gutter between boxes that isn't used?

I ask because I'd laid down a 1-pixel white grid to seperate boxes so I could see how centered I had icons, and when I left that grid in the final .dds file I ended up with 2 edges just barely visible in the displayed icons on the map. Changing the alpha channel so the grid was transparent cleared that up, but I'm wondering if I got my origin off so my boxes are 1 pixel off from where I think they are.

Thanks.
