Win32 + OpenGL bindings

[Diggory]

I've been trying to write a win32 app using opengl in D, but none 
of the bindings I've found have been sufficient:

- core.sys.windows.windows:
Missing large parts of wingdi.h, including PFD_* constants, 
ChoosePixelFormat(), SwapBuffers(), wgl*() functions.

- win32.windows:
Apparantly out of date and gives linker errors, although it does 
declare all the functions needed.

- derelict.util.wintypes:
Declares a small number of useful windows functions, many of 
which conflict with those declared in "core.sys.windows.windows" 
(such as PIXELFORMATDESCRIPTOR). However, "SetPixelFormat" is not 
declared.

- derelict.opengl.gl:
Has all of opengl plus wgl* functions needed for windows, but has 
more dependencies than an ideal opengl binding would have.

Why isn't there a simple relationship between C/C++ header files 
and D modules, instead of this weird mix where some things are 
duplicated and others not declared at all?

All of the windows specific functions including wgl* are supposed 
to be in "windows.h", and opengl functions in "gl/gl.h"

It's a shame because I really like the ideas behind D - in fact 
the reason I found it is that I'd come up with a whole bunch of 
ideas I wanted in an ideal language and it turned out D already 
implemented them all...
