Further information provided by Cho Seungbo on 10 January 2012:

I changed just these values

#define SWSnapshotStackViewMatteWidth 3.0

// SINGLE DISPLAY MODE CONSTANTS
//! Defines X offset for either edge to indent shadow effect (single mode)
#define SWSnapshotStackViewSingleShadowXOffset 0.0
//! Defines Y offset to drop shadow below snapshot matte frame
#define SWSnapshotStackViewSingleShadowYOffset 0.0
//! Defines radius of the shadow (results in magnitude and softness of shadow)
#define SWSnapshotStackViewSingleShadowRadius 1.0

and then I moved slider control of your sample app.

Actually, when I used original values, the margins are not same. Left and Top margin is bigger than
right and bottom margin. If you use small value for SWSnapshotStackViewMatteWidth, you can find
the gap of margin more easily.
