Map by -MP-zunnie.
The original map this is based on
is fy_iceworld_cssource
Some newbie mapper ported the original
version from CS16 to CSS, without
setting up any VIS Sectors so that
stuff you cant see is not rendered etc,
due to this it lagged the fuck out of 
everyone...
Made several performance updates and
adjusted some other things too.

Changes relative to original version:

-Made it a bit bigger
-Changed lighting.
-Removed autosniper from spawning.
-More player spawnpoints.
-More weapon spawnpoints.
-Added the water in center with 'ice' on top like in the original.
-Improved performance by marking textures as "no draw" (things you can NEVER see at all wont be redered anymore = more FPS)
-Improved performance by setting up VIS Sectors. (things you cant see dont render anymore = more FPS)
-Changed texturing.
