!!! float terrainHeight[300][300] !!!

300x300 is too small in high detail terrain mode. I modified it in 450x450 and 
recompiled. Now seems to work fine on my tracks.
I compiled it on MinGW GCC 4.5.2. 
I attach the compiled library and header. 

!!! Be Careful !!! Not fully Tested yet...

... dont know if providing compiled library violates the license statements. I 
removed the files. Sorry.
