This is the same as _cogl_read_pixels except that it takes a rowstride parameter for the destination buffer. Under OpenGL setting the rowstride this will end up calling GL_ROW_LENGTH so that the buffer region can be directly written to. Under GLES GL_ROW_LENGTH is not supported so it will use an intermediate buffer as it does if the format is not GL_RGBA. cogl_read_pixels now just calls the full version of the function with the rowstride set to width*bpp. http://bugzilla.clutter-project.org/show_bug.cgi?id=2414
