Inappropriate field type in WINDOWPLACEMENT

[Enyium]

GetWindowPlacement() and SetWindowPlacement() handle a WINDOWPLACEMENT struct. showCmd is a u32, but it should be a SHOW_WINDOW_CMD, because the values that it may contain like, e.g., SW_SHOWMINIMIZED are of that type.

We can't do that, sadly. See related issue #1502 for the details.

The short version is: showCmd is u32 while SW_SHOWMINIMIZED et al. are integer literals in the original C/C++ headers (i.e., #define SW_SHOWMINIMIZED 2). Those default to int. We have to preserve these types for application binary interface (ABI) correctness.

Projections (e.g., C#, Rust) can opt into reading the associated enum attribute value and generate any desired overloads, wrappers, etc.

public struct WINDOWPLACEMENT
{
...
	[AssociatedEnum("SHOW_WINDOW_CMD")]
	public uint showCmd;
...

Closing for now but feel free to keep the discussion going.
