Using calloc() instead of malloc() as preventive measure, so there
never can be any hidden bugs or leaks due uninitialized memory.
The extra cost of using this compiler intrinsic should be practically
impossible to measure - in many cases a good compiler can even deduce
if certain areas really don't need to be zero'd (because they're written
to right after allocation) and create more efficient machine code.
The code pathes in question are pretty cold anyways, so it's probably
not worth even thinking about potential extra runtime costs.

Some Win32 API types are different fundamental types in the 32-bit and 64-bit
versions.
This problem is then further compounded by the fact that whilst both 32-bit
Cygwin and 32-bit MinGW use the ILP32 data model, 64-bit MinGW uses the LLP64
data model, but 64-bit Cygwin uses the LP64 data model.
This makes it impossible to write printf format specifiers which are correct for
all those targets
In the Win32 API, DWORD is an signed, 32-bit type. It is defined in terms of a
long, except in the LP64 data model, where it is an int.
It should always be safe to cast it to int and use %d.

winOverrideIcon() is called from the internal WM client thread.
Accessing server-internal data structures to get icon data or window hints is
not safe, as there is no lock to ensure we do not collide with these data
structures being updated in the server thread.
Rewrite so the internal client thread uses X client calls to obtain this data
safely
We used to also set the icon inside the server when the window was initially
created. For simplicity, we simply send a message to the internal WM to update
the icon when the window is created (rather than writing different icon update
code which can work in the server thread for that one case...)
extwm mode used to do the icon update in the server. I'm not sure that actually
made much sense. Let's assume the external WM client can do it instead...
v2
Make sure that WM_WM_ICON_EVENT does nothing for override-redirect windows
v3

window before trying to update it's icon; some auxiliary windows owned by the

- don't try to retrieve WM_HINTS icon_mask if it isn't set
- restore accidentally dropped calculation of effBpp, stride, maskStride of output DDBitmap
- make sure imageMask is zero-initalized before we use it to mask the DDBitmap

The WIN_WINDOW_PROP is removed during WM_DESTROY handling, so it is not neccessary to
remove it in winDestroyWindowsWindow(), and doing so opens a race condition, as we may
attempt to access that property in the wndproc before the WM_DESTROY has completed.
A specific example of that race is if a WM_KILLFOCUS occurs in the window between property
removal and WM_DESTROY processing, where we will attempt to apply DeleteWindowFromAnyEvents()
on an invalid (null) WindowPtr.
Also guard against null WindowPtr in the WM_KILLFOCUS handler

When the style changes, adjust the window size so the client area remains the same.
Otherwise the window size may change when sizing is reflected from Windows to X, and
some windows are drawn expecting them to be exactly the requested size (e.g. the
gmplayer control window)
Use DeferWindowPos to delay the resize to preserve client area on WM_STYLECHANGING
until after the style change has actually happened in WM_STYLECHANGED
As a consquence of this, we need to be more careful to create windows with exactly
the requested placement and client area initially, so the client area matches what
the X client requested
Also synchronize the X windows idea of the placement of a window which Windows is
allowed to place
