[fpc-pascal]DirectX8 D3D headers converted to FPC.

[Eero Tanskanen]

I converted the Delphi conversions (thanks to Alexey Barkovoy of Delphi-Jedi
for it) of DirectX8 D3D (only D3D part) to fpc-compliant and it seems to
work all right with the 2 first D3D tutorials in DX8 SDK. If anyone wants a
copy of it, send me an email.
