The following objects now have properties that can be user modified:
* SDL_AudioStream
* SDL_Gamepad
* SDL_Joystick
* SDL_RWops
* SDL_Renderer
* SDL_Sensor
* SDL_Surface
* SDL_Texture
* SDL_Window
Also switched the D3D11 and D3D12 renderers to use real NV12 textures for NV12 data.
The combination of these two changes allows us to implement 0-copy video decode and playback for D3D11 in testffmpeg without any access to the renderer internals.
Whenever I have to fix something endianness-related, I always get
confused about whether the byte-oriented format that guarantees to put
red in byte 0 is RGBA8888 or RGBA32. (The answer is that it's RGBA32.)

This is essentially the same as was added in d95d2d70, but with clearer
error handling. It's implemented in a private header file so that it
can be shared with SDL_shape, which also wants this functionality.

This fires if an opened device changes formats (which it can on Windows,
if the user changes this in the system control panel, and WASAPI can
report), or if a default device migrates to new hardware and the format
doesn't match.
This will fire for all logical devices on a physical device (and if it's
a format change and not a default device change, it'll fire for the
physical device too, but that's honestly not that useful and might change).
Fixes#8267.
Now it offers the total requested bytes in addition to the amount
immediately needed (and immediately needed might be zero if the stream
already has enough queued to satisfy the request.
You can see it in action in testaudio by mousing over a logical device; it
will show a visualizer for the current PCM (whatever is currently being
recorded on a capture device, or whatever is being mixed for output on
playback devices).
Fixes#8122.
On some system like MacBook Pro Intel with AMD card, asking for the default device will always return the AMD GPU.
This is not an issue for 99% of the case when the renderer context is here to provide the maximum performance level like for game.
However, for video application using GPU for 1 quad and 1 texture, using the discrete GPU for that lead to an important power consumption (4 to 8W), heat increase, and fan noise.
With this patch, I successfully amend ffplay to only use the integrated GPU (i.e. the Intel one), instead of the discrete GPU (i.e. the AMD one).
This is meant to offer a simplified API for people that are either migrating
directly from SDL2 with minimal effort or just want to make noise without
any of the fancy new API features.
Users of this API can just deal with a single SDL_AudioStream as their only
object/handle into the audio subsystem.
They are still allowed to open multiple devices (or open the same device
multiple times), but cannot change stream bindings on logical devices opened
through this function.
Destroying the single audio stream will also close the logical device behind
the scenes.
