// This is the hysteresis value for collapsing/expanding subviews with the mouse. 0.05 (5%) works well.
#define HYSTERESIS (0.05)

// This selects the main horizontal or vertical coordinate according to the split view's orientation.
// It can be used as an lvalue, too. You need to have BOOL ishor declared to use it.
#define DIM(x) (((CGFloat*)&(x))[ishor])

// This selects the other coordinate. You need to have BOOL ishor declared to use it.
#define OTHER(x) (((CGFloat*)&(x))[!ishor])

// This value for the view offsets is guaranteed to be out of view for quite some time and is used
// to mark the view as collapsed.
#define WAYOUT (1000000.0)

// This is the default framerate for collapse/expand animation.
#define FRAMETIME (1.0/60.0)
