Otherwise, the callback is invoked after the overlayer is redrawn.

// The flags below provide additional information to define the moment when
// callback was invoked in redraw procedure. These flags are bitwise OR'ed
// with the "reason" value of callback:
// 1) OCC_PRE_REDRAW - callback was invoked before redrawing underlayer
// ( at the beginning of redraw procedure );
// 2) OCC_PRE_OVERLAY - callback was invoked before redrawing overlayer;
// Otherwise, if no flags added to the "reason" value, the callback was
// invoked at the end of redraw ( after the overlayer is redrawn )
#define OCC_PRE_REDRAW 0x4000
#define OCC_PRE_OVERLAY 0x8000
// mask for all additional callbacks that invoked in process of redrawing
#define OCC_REDRAW_ADDITIONAL_CALLBACKS ( OCC_PRE_REDRAW | OCC_PRE_OVERLAY )
