Subject: SDL CVS patches

below you will find some small patches against the
current SDL CVS.

It adresses these things:

1) Use "&" instead of "%" in some cases. For negative
   signed integers (x % 8) is not always (x & 7),
   and the compiler can produce slightly faster
   code when using "&" here.

2) Some const issues.
