Documentation on DIBENG.DLL exported functions

[Alex Villací­s Lasso]

Could somebody please point me to an online documentation on the 
functions exported by DIBENG.DLL and how an userspace application could 
use them? I want to evaluate whether a possible DIB engine for Wine 
could use the DIBENG.DLL API. I googled and all I find are reports of 
GPFs involving DIBENG.DLL. Same issue when searching MSDN. Of course, 
DIBENG.DLL might not be the best model to implement for a DIB engine, so 
I wait for suggestions. I was planning on writing a C program that would 
load DIBENG.DLL via LoadLibrary() and call its functions in order to 
build tests for it.
