SlimDX files

There are 3 files (for slimDX) being shipped with Nvil:-

SlimDX.dll
SlimDX.pdh
SlimDX.xml

As I was checking Nvil, I noted that those 3 files are not being accessed by Nvil. So I am curious as to the reason for them being included with the Nvil download. [I have now deleted them from Nvil folder.]

Needed files for SlimDX are installed to user system with the (SlimDX) prerequisite installation.
