The function is exported by name from shell32 and declared in a public
header.

Hopefully useful for people like me who had a hard time understanding
what was going on. Especially with the rearranged divison and the
simplification I had a hard time seeing why that does what it does

If TransformView_Create returns an error, it should not return a pointer
that table_load_transform will try to free.

Fixes double frees in read_components and read_dependency. The double
frees could also be fixed by using free instead of free_dependency in
those functions, but zeroing out the pointers is easier to understand
because it ensures that alloc_dependency can always be paired with
free_dependency.

Fix memory leaks on error paths, don't call memset unnecessarily, and
ensure that all output fields are initialized.

We don't need the window anymore, it was only used to send ClipCursor
notifications. This improves cursor clipping performance a lot as it
avoids re-creating a window every time.

If the focus changes between Wine windows, the wineserver logic will
decide to reset the clipping rectangle. However winex11 also needs to
support the case when focus changes to a host window, in virtual desktop
mode, and in this case the foreground window doesn't actually change.

To fix this, in virtual desktop mode, release the cursor on focus out
events, and reapply the cursor clipping rect when the virtual desktop
window is focused again.

We can use the same logic on NotifyGrab events, when the WM grabs the
keyboard, and later reapply the Wine clipping rect when we are notified
about the keyboard ungrab.

This might be the case when in virtual desktop mode for instance, where
we don't change Wine foreground window when the virtual desktop is
focused out.
