[ka-Map-users] Bug in label rendering

[Loïc MAZE]

I have increased the value of the $tileBuffer var in the tile_nocache.php 
file and it works perfectly now. This var seems to have the same purpose as 
the $metaBuffer var in the tile.php file. Sorry for the warning and hope 
this will be helpful for the others. Maybe it will be interesting the 
$tileBuffer var receive the same value as the $metaBuffer var (in config.php 
file).

Regards,
Loïc
