Ah, that's probably where 0.125 comes from - 1/8th for 8x MSAA.
Though we advertise 1.0 as the minimum MS point width, as well.
I suppose we could try and advertise 0.125 as the minimum MSAA point
width in GLES, and use 0.125 for MSAA and 1.0 for single sampled RTs.
Advertising in GL is a bit won
Do smaller point sizes make sense when multisampling?

We advertise 1.0 as the minimum point width size, and we probably ought
to clamp gl_PointSize to the actual range we advertise ([1,255]). In
particular, we don't seem to rasterize any points if the shader outputs
a point size smaller than 1.0, and that seems rather sketchy.
This fixes Piglit's vs
