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.
