//	Desc	: Expose external functions of the 2D Game Framework 
//		Stage manager. This manager handles high level visuals. 
//		It determines the scaling for stage co-ords and physical pixels
//		It also moves the camera around the stage. ( The camera view is 
//		the actual physical display ).

// Function : fwStageGetPixelShift 
// Parameters
// Returns
// int      : Virtual co-ord to pixel shift value. Number if bits to right shift
//	a virtual value to produce a physical value.

// Function : fwStageSetPixelShift 
// Parameters
// shift    : Number of Right Bit shifts to apply to virtual co-ords to 
//	give a physical co-ords.
// Returns

// Function : fwStageGetCameraLeftPos 
// Parameters
// Returns
// int      : Virtual xpos of left side of camera view

// Function : fwStageGetCameraTopPos 
// Parameters
// Returns
// int      : Virtual ypos of top side of camera view

// Function : fwStageSetCameraTop 
// Parameters
// yPos     : Set Virtual yPos for top of camera
// Returns

// Function : fwStageSetCameraTopLeft 
// Parameters
// yPos     : Set Virtual yPos for top of camera view on stage
// xPos     : Set Virtual xPos for left of camera view on stage
// Returns

// Function : fwStageSetWidth 
// Parameters
// width    : Define the virtual width of the stage.
//	This is used to limit camera positions.
// Returns

// Function : fwStageSetHeight 
// Parameters
// height   : Define the virtual height of the stage.
//	This is used to limit camera positions.
// Returns

// Function : fwStageSetSize 
// Parameters
// width    : Define the virtual width of the stage.
//	This is used to limit camera positions.
// height   : Define the virtual height of the stage.
//	This is used to limit camera positions.
// Returns
