Installs the given program3D as a part of the current rendering state.

Validates the given program3D. The validation status is stored into the state of the shader program container in program3D and can be queried using Context3D.VALIDATE_STATUS as paramName for Context3D.getProgramParameter() method. Additional information may be stored into the program's information log.
