unsigned short in Python 2.0

[Michel Sanner]

Hi,

I tried my PuOpenGL graphics tools out under Python2.0 and found some
differences with Python 1.5.2

it seems that with Python 1.5.2 it was possible to pass an unsigned short value
to a function expecting a short. This is used in _openglmodule.c, for instance

static PyObject* gl_LineStipple(PyObject* self, PyObject* args)
{
	GLint arg1;
	GLushort arg2;
	TRY (PyArg_ParseTuple(args, "ih", &arg1, &arg2));
  	glLineStipple(arg1, arg2);
	Py_INCREF(Py_None);
	return Py_None;
}

Python 1.5.2 (#0, Apr 14 2000, 10:15:38) [C] on irix646
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
IDLE 0.5 -- press F1 for help
>>> from OpenGL import GL
>>> GL.glLineStipple(1.0, 0xFFFF)

No problem

under python2.0 passing anything larger than 2**15-1 creates a overflow
exception (I think in PyArg_ParseTuple).

>>> from OpenGL import GL
>>> GL.glLineStipple(1.0, 0xFFFF)
Traceback (innermost last):
  File "<pyshell#2>", line 1, in ?
    GL.glLineStipple(1.0, 0xFFFF)
OverflowError: signed short integer is greater than maximum
>>>

I could not see how to specify an unsigned short in the documentation :( ..
