// D3DXCreateEffect:
// -----------------
// Creates an effect from an ascii or binaray effect description.
//
// Parameters:
//  pDevice
//      Pointer of the device on which to create the effect
//  pSrcFile
//      Name of the file containing the effect description
//  hSrcModule
//      Module handle. if NULL, current module will be used.
//  pSrcResource
//      Resource name in module
//  pSrcData
//      Pointer to effect description
//  SrcDataSize
//      Size of the effect description in bytes
//  ppEffect
//      Returns a buffer containing created effect.
//  ppCompilationErrors
//      Returns a buffer containing any error messages which occurred during
//      compile.  Or NULL if you do not care about the error messages.
