There were several good arguments for this: it's how Windows works with
WM_NCHITTEST, SDL doesn't need to manage a list of rects, it allows more
control over the regions (how do you use rects to cleanly surround a circular
button?), the callback can be more optimized than a iterating a list of
rects, and you don't have to send an updated list of rects whenever the
window resizes or layout changes.
This should be a "long" which on a 64-bit system is likely to be > 32-bits,
causing XGetICValues() to write past the end of the variable (and stack).
Fixes Bugzilla #2513.
All WinRT builds of SDL will now output, "SDL2.dll". Previously, the Windows
8.x/RT builds would output, "SDL.dll", and Windows Phone 8 builds would output,
"SDL_WinPhone.dll". The change to "SDL2.dll" puts WinRT dll naming in-line with
that seen on Win32.
SDL/WinRT's MSVC project files will now appear as either "SDL2-WinRT" or
"SDL2-WinPhone", when displaying in MSVC.
This set of changes should not break any older WinRT or Windows Phone 8 app
builds that rely on MSVC's Project-to-Project reference system to build SDL2 for
the correct platform(s), and to install SDL2 dll files into the apps' output
packages. App builds that reference SDL dll files directly should, however,
now reference "SDL2.dll".
It seems like a net improvement in all the scenarios Sam and I could
think of, and looking at hg history it was added for fullscreen
window management specifically. Much of that code has changed since
then, but maybe it needs to stay there for that and simply be moved
to a fullscreen condition check.
It would solve this issue:

As well as cases where on SteamOS, we hide/show specific Steam
overlay windows while expecting them to stay in the background, since
changing the window stacking order really angers the NVIDIA driver.
CR: Sam.
(Most of its complaints here are that these ints can be negative, although
they wouldn't been in sane cases. Checking sanity is what assertions do, and
it placates the analyzer appropriately.)
These scenarios can happen when a GPU is switched, its driver updated, or in
some virtual machines (such as Parallels) are suspended and then resumed. In
these cases, all GPU resources will already be lost, and it's up to the app to
recover.
For now, SDL's D3D11 renderer will handle this by freeing all GPU resources,
including all textures, and then sending a SDL_RENDER_TARGETS_RESET event.
It's currently up to an app to intercept this event, destroy all of its
textures, then recreate them from scratch.
SDL_WINDOWEVENT_FOCUS_LOST is now sent when an app's native window is hidden.
Likewise, SDL_WINDOWEVENT_FOCUS_GAINED is sent when an app's window is shown.
This mimicks behavior seen on iOS and Android.
SDL_WINDOWEVENT_MINIMIZED and SDL_WINDOWEVENT_RESTORED are now sent when the
app's native window is hidden and shown. Previously, these were sent when an
app was suspended and resumed. On Windows 8.x/RT, an app may be sent to the
background without being suspended, which previously meant that
SDL_WINDOWEVENT_MINIMIZED might never have been sent. (On Windows Phone 8,
however, this seems to be different, whereby apps sent to the background appear
to always get suspended.)
