Cropping window outside main window.

For several versions Wine does not properly show several pieces of information
for Nikon NX Studio:

- Cropping tool overlay
- Image Histogram
- Image information.

The problem is that the overlays are outside of the main window and seem to be
positioned at (0, 0). This documentation show how it should look like:

- https://nikonimglib.com/nxstdo/onlinehelp/en/the_bottom_toolbar_11.html
- https://nikonimglib.com/nxstdo/onlinehelp/en/cropping_pictures_38.html

The histogram and image information screens however look like this:
https://bugs.winehq.org/attachment.cgi?id=77257. I attach an image of how the
cropping window looks like. One can see a transparent overlay that is meant to
darken the image and the currently selected area in the middle. I can change
the inner part of the crop by holding the left mouse button and moving over the
picture (not the window outside of the picture).

All three overlays are transparent and use EX_WS_LAYERED. This excerpt from
winedbg shows the window hierarchy:

Info Screen and Histogram Screen are children of Image Screen and Image Panel.
I assume one of the two is the picture area in the main window. As children
they should be positioned relative to the parent and be moved together with it.

xwininfo gives the following output on the CropScreen:

One additional aspect of the problem is that the overlay windows are always on
top even if the main window is minimized.

When I run inside of a virtual dekstop the overlays show as black windows and
they are also outside of the main window:

--- Comment #1 from Christoph Bartoschek  ---
I have created a small testcase program that reproduces the problem and attach
it to the bug. This is how I compile the program:

tar -xzf testcase-layered-window.tgz
cd testcase-layered-window
x86_64-w64-mingw32-windres main.rc  -o manifest.o
x86_64-w64-mingw32-c++ -static  -mwindows  main.cc manifest.o -lgdi32 -o
testcase-layered.exe
wine testcase-layered.exe

When run the program shows a window with a green box. On top of the green box
there should be a red layered window with alpha=128. However the layer is not
positioned on top of its parent window but at the absolute top. I also attach
an image of how this looks like under wine and how it looks on Windows 11
(running under VirtualBox)
