Summary: glGetIntegerv(GL_SMOOTH_LINE_WIDTH_RANGE) result changed

Initial Comment:
In some code that I work with, we call glGetIntegerv(GL_SMOOTH_LINE_WIDTH_RANGE). This used to return an array, so we would later do essentially lineWidth[1] to get the max width and use that.

With PyOpenGL on Windows, that seems now to return a single integer -- at least, when we try to index it, we get an error like this:
    IndexError: invalid index to scalar variable.

Is this expected? Where can we get the old value? The single value that's returned now seems to be only the low end of the range ...

Message:
Note that changing to use GL_LINE_WIDTH_RANGE (which should in theory be an
alias) seems to work on both 3.0.0 and 3.0.1.

I suspect there's a bug in glget.py where GL_SMOOTH_LINE_WIDTH_RANGE is
defined to have dimensions (1,) ...
