I recall reading somewhere a long time ago regarding a 1px transparent pixel border that construct adds for images, but I don't seem to be able to find it anymore.
The reason I am asking was because I forgot the implications... for example should I be importing bitmaps at 512x512, or 510x510?
Or maybe did it have something to do with resized images or seamless tiling or 9patch? I can't remember!
I know I was having some issues with 9patch using exact pixels with solid colors and not leaving space around the edges, or similar when I make a solid color sprite square and down size it in the image editor, the edges pixels get changed to semi transparent. Are these related?
