don't have them larger than 1, since vertices are drawn with it.
It is solved by patching code with minimal confusement. So you can get
automatic patched glPoints with:
bglBegin(GL_POINTS);
bglVertex3fv(vector);
bglEnd();
In glutil.c the wrapper can be found, that checks for maximum Pointsize,
and bypasses it to a glBitmap then.
