Currently, you cannot set negative values for the Size and Position Options inside of Object Styles.

This is an obvious error because sometimes, you need a class of objects to bleed. For example, I would like a ImageFullpage style that I could use to set images that bleed on all four sides.

This requires that they be positioned at -0.125 x and 0.125 y.

Also, an ImageCaption style that sets a caption on top of an image should allow me to use -y: .125. When combined with the bottom reference point and the from: "group" option (another request), it would set the caption so that the bottom was aligned 0.125 Inches above the image easily.
