At startup GtkD searches the Path for "libgtk-3-0.dll", when it finds 
one it checks the architecture of the library. If it's the correct 
architecture it calls `SetDllDirectory` so that the directory with the 
correct architecture will be searched first by `LoadLibrary`.

If it's not the correct architecture it continues searching, if no 
library with the correct architecture is found, we rely on `LoadLibrary` 
to error out if the libraries are also not in the other locations 
searched by `LoadLibrary`.
