I tested the above line on my ATI card. Makes absolutely no difference, 
neither visually, nor performance wise.
But GL_POINT_SPRITE is only defined in glATI.h on my system, so I had to 
add it to SimGear/simgear/screen/extensions.hxx
In glext.h I find only GL_POINT_SPRITE_ARB which has the same value.
