Hello everyone!
I have encountered a problem on using VMR9AlphaBitmap structure in
"vmr9.h". According to
https://docs.microsoft.com/en-us/windows/win32/directshow/directshow-structures
, the `rDest` field of the structure is 'immediate', though the current
mingw-w64 definition is a pointer. Actually, I can use the structure
with no problem only if I modify it to the immediate one.
At first, I tried generating "vmr9.h" from "vmr9.idl" by WIDL 5.0-rc1, but
some declarations in the generated header changed from WINBOOL to BOOL..
WINBOOL seems desirable according to mailing list logs, so I have edited
it without WIDL.
