void	ClampCameraToTileLayer (struct GameLayer2DData *pGameLayerData, int tileLayerNum)
	Make it so no matter where move the camera nothing outside the layer is visible. If the layer is smaller than the camera bounds the camera position is fixed in the centre.
void	UpdateCameraClamp (struct GameLayer2DData *pGameLayerData)
	Update the camera position to be clamped, if a clamp is set.

CenterCameraAt()

void CenterCameraAt	(	float	worldspaceX,
		float	worldspaceY,
		struct Transform2D *	pCam,
		int	winWidth,

ClampCameraToTileLayer()

void ClampCameraToTileLayer	(	struct GameLayer2DData *	pGameLayerData,
