// rid of all of them and then it will be easy to find all occurrences of their
// use by just searching for this namespace name.
//
// All of the functions in this namespace must work *exactly* like the standard
// functions with the same name and just return an error if dynamically loading
// them failed.
//
// And they're all implemented in src/msw/dc.cpp.
