@ Ben Klein: I am sorry, I am new to Bugzilla. Bear with me as I take you
through the problem.

@ Jeff Zaroyko: I'm sorry - I also confirmed this bug to be present in 1.1.30.

I also researched the etiology: apparently, glPointSize returns a value of
0x501 (1 * 16^0 + 5 * 16^2 = 1281 in decimal numbers), while antialiasing is
enabled. If antialiasing is enabled, OpenGL does not allow an infinite range of
point sizes (source:
http://www.opengl.org/documentation/specs/man_pages/hardcopy/GL/html/gl/pointsize.html
).

I do not know the range of valid point sizes, as it is defined in the program.
The only constant about point size ranges is whether the driver allows point
sizes < 0, and that differs among drivers too.
I'm digging through the source code now to try and find the range of valid
point sizes.
