+ * This function is roughly equivalent to:
+ *
+ * ```c
+ * SDL_OpenAudioDevice(NULL, 0, desired, obtained, SDL_AUDIO_ALLOW_ANY_CHANGE);
+ * ```
+ *
+ * With two notable exceptions:
+ *
+ * - If `obtained` is NULL, we use `desired` (and allow no changes), which

+ * - The return value is always success or failure, and not a device ID, which

+ * The functions SDL_SetRenderDrawBlendMode and SDL_SetTextureBlendMode accept

+ * A blend mode controls how the pixels from a drawing operation (source) get

+ * blend factors. Then, the blend operation takes the two products and
+ * calculates the result that will get stored in the render target.
+ *
+ * Expressed in pseudocode, it would look like this:
+ *
+ * ```c
+ * dstRGB = colorOperation(srcRGB * srcColorFactor, dstRGB * dstColorFactor);
+ * dstA = alphaOperation(srcA * srcAlphaFactor, dstA * dstAlphaFactor);
+ * ```
+ *
+ * Where the functions `colorOperation(src, dst)` and `alphaOperation(src,

+ *
+ * - `src + dst`
+ * - `src - dst`
+ * - `dst - src`
+ * - `min(src, dst)`
+ * - `max(src, dst)`
+ *
+ * The red, green, and blue components are always multiplied with the first,
+ * second, and third components of the SDL_BlendFactor, respectively. The
+ * fourth component is not used.
+ *
+ * The alpha component is always multiplied with the fourth component of the
+ * SDL_BlendFactor. The other components are not used in the alpha
+ * calculation.
+ *
+ * Support for these blend modes varies for each renderer. To check if a
+ * specific SDL_BlendMode is supported, create a renderer and pass it to
+ * either SDL_SetRenderDrawBlendMode or SDL_SetTextureBlendMode. They will
+ * return with an error if the blend mode is not supported.
+ *
+ * This list describes the support of custom blend modes for each renderer in
+ * SDL 2.0.6. All renderers support the four blend modes listed in the

+ * - **opengl**: Supports the `SDL_BLENDOPERATION_ADD` operation with all

+ *   2.0.6.
+ * - **opengles**: Supports the `SDL_BLENDOPERATION_ADD` operation with all
+ *   factors. Color and alpha factors need to be the same. OpenGL ES 1
+ *   implementation specific: May also support `SDL_BLENDOPERATION_SUBTRACT`
+ *   and `SDL_BLENDOPERATION_REV_SUBTRACT`. May support color and alpha
+ *   operations being different from each other. May support color and alpha
+ *   factors being different from each other.
+ * - **opengles2**: Supports the `SDL_BLENDOPERATION_ADD`,
+ *   `SDL_BLENDOPERATION_SUBTRACT`, `SDL_BLENDOPERATION_REV_SUBTRACT`
+ *   operations with all factors.
+ * - **psp**: No custom blend mode support.
+ * - **software**: No custom blend mode support.
+ *
+ * Some renderers do not provide an alpha component for the default render
+ * target. The `SDL_BLENDFACTOR_DST_ALPHA` and
+ * `SDL_BLENDFACTOR_ONE_MINUS_DST_ALPHA` factors do not have an effect in this

+ *
+ * The DRM subsystem has a concept of a "DRM master" which is a DRM client that
+ * has the ability to set planes, set cursor, etc. When SDL is DRM master, it
+ * can draw to the screen using the SDL rendering APIs. Without DRM master, SDL
+ * is still able to process input and query attributes of attached displays,
+ * but it cannot change display state or draw to the screen directly.
+ *
+ * In some cases, it can be useful to have the KMSDRM backend even if it cannot
+ * be used for rendering. An app may want to use SDL for input processing while
+ * using another rendering API (such as an MMAL overlay on Raspberry Pi) or
+ * using its own code to render to DRM overlays that SDL doesn't support.
+ *
+ * This hint must be set before initializing the video subsystem.

+ *  a DPI scale factor.
  *
-*  2. The flag SDL_WINDOW_OPENGL will be set on the new window so it can be used for
-*  OpenGL rendering.
+ *  This hint is equivalent to requesting DPI awareness via external means (e.g. calling SetProcessDpiAwarenessContext)

- *  \brief  A variable controlling speed/quality tradeoff of audio resampling.

- *  to handle audio resampling. There are different resampling modes available
- *  that produce different levels of quality, using more CPU.
- *
- *  If this hint isn't specified to a valid setting, or libsamplerate isn't

+ *  \brief  A variable that forces X11 windows to create as a custom type.
  *
- *  Note that this is currently only applicable to resampling audio that is
- *  being written to a device for playback or audio being read from a device
- *  for capture. SDL_AudioCVT always uses the default resampler (although this
- *  might change for SDL 2.1).
+ *  This is currently only used for X11 and ignored elsewhere.
  *
- *  This hint is currently only checked at audio subsystem initialization.
+ *  During SDL_CreateWindow, SDL uses the _NET_WM_WINDOW_TYPE X11 property
+ *  to report to the window manager the type of window it wants to create.
+ *  This might be set to various things if SDL_WINDOW_TOOLTIP or
+ *  SDL_WINDOW_POPUP_MENU, etc, were specified. For "normal" windows that
+ *  haven't set a specific type, this hint can be used to specify a custom
+ *  type. For example, a dock window might set this to
+ *  "_NET_WM_WINDOW_TYPE_DOCK".
  *
- *  This variable can be set to the following values:
+ *  If not set or set to "", this hint is ignored. This hint must be set
+ *  before the SDL_CreateWindow() call that it is intended to affect.
  *
- *    "0" or "default" - Use SDL's internal resampling (Default when not set - low quality, fast)
- *    "1" or "fast"    - Use fast, slightly higher quality resampling, if available
- *    "2" or "medium"  - Use medium quality resampling, if available
- *    "3" or "best"    - Use high quality resampling, if available

+ *  The default value is "1".  This hint can be changed at any time.
  *
- *  Up to SDL 2.0.9, the render API would draw immediately when requested. Now

- *  render backend is requested (since this might indicate that the app is
- *  planning to use the underlying graphics API directly). This hint can
- *  be used to explicitly request batching in this instance. It is a contract
- *  that you will either never use the underlying graphics API directly, or
- *  if you do, you will call SDL_RenderFlush() before you do so any current
- *  batch goes to the GPU before your work begins. Not following this contract
- *  will result in undefined behavior.
