But no matter what I do, (and I've tried everything) I can't seem to get my icons to center align with the button. it is always about 2 or 3 pixels to the right. You can see here:

The stock icons are 18px x 18px and any icon that size is automatically centered, but anything bigger than that get's off to the right just the littlest bit.

I've tried 36px icons and 50px icons.

Any ideas?
