Detailed Description
Stores the current projection matrix.
This element stores the current projection matrix - the projective part of the matrix set up by the camera. Because most operations on this matrix are atomic, it is considered a non-accumulating element.

Sets the projection matrix to the given matrix.
This method will (indirectly) call glLoadMatrix with the new matrix unless the 'sendToGL' parameter is explicitly FALSE.
