How do native win32 apps end up calling into x11drv?

[Adam Connell]

Greetings,

I'm trying to understand how windows drawing gets translated into X in wine
and so I was looking at the {im,ex}ports of x11drv and gdi32. x11drv depends
on gdi32 and just seems to export a good chunk of the api that gdi32 exports
(BitBlt etc). gdi32 doesn't depend on x11drv or even Xlib. How do native 
win32
apps end up calling into x11drv?

Cheers,
Adam
