Parameters:

pname - GL_MODELVIEW_MATRIX, GL_PROJECTION_MATRIX or GL_TEXTURE_MATRIX

params - storage

params_offset - storage offset

glGetIntegerv

void glGetIntegerv(int pname,
                   IntBuffer params)

glGetIntegerv

Parameters:

pname - GL_MATRIX_MODE to receive the current matrix mode

params - the FloatBuffer's position remains unchanged which is the same behavior than the native JOGL GL impl
