Fix EffectPass.cs #2
Description
EffectPass.cs uses lots of IntPtrs, and we no longer can pass those to SharpDX. It is possible that the whole file needs to be rewritten.
Commit "HACK: unimplemented and hack Toolkit changes" adds a few workarounds, but those create new objects at every call and are quite bad. Also some parts are #if'ed out as there didn't seem to be public APIs in SharpDX to do the work.
