Point size, like the number of texture units, has a queryable maximum.
The radeon and r200 drivers advertise the maximum as 1.0.  Your program
is buggy in that it ignores the driver advertised maximum.  'glxinfo -l
| grep POINT_SIZE' will show you the relevant limits supported by the
driver.

That said, there were some patches floating around *years* ago that
exposed larger point sizes.  I could have sworn that those got
committed.  Does anyone know the status of those patches?
