[Mono-dev] How to access XplatUI for custom controls?

I could not get your assembly to build with the following errors:
MonoNativeCalls.cs(544,45): error CS0122: `System.Windows.Forms.MSG' is
inaccessible due to its protection level
In addition, it seems like the code in "XplatUI\ Custom.cs" calls
itself, so this would just end up with stack overflows. I did not find
any reference to XplaUIWin32 either.
I rather include the code from ../System.Windows.Forms/* with a
namespace change if needed than duplicate that code. I did that for your
structs (you can see the changes on the 2.8 and master branches) by using
the PUBLIC_TYPES define.
