+ *
+ * The file I/O (for example: SDL_RWFromFile) and threading (SDL_CreateThread)
+ * subsystems are initialized by default. Message boxes
+ * (SDL_ShowSimpleMessageBox) also attempt to work without initializing the
+ * video subsystem, in hopes of being useful in showing an error dialog when

+ *
+ * - `SDL_INIT_TIMER`: timer subsystem
+ * - `SDL_INIT_AUDIO`: audio subsystem
+ * - `SDL_INIT_VIDEO`: video subsystem; automatically initializes the events
+ *   subsystem
+ * - `SDL_INIT_JOYSTICK`: joystick subsystem; automatically initializes the
+ *   events subsystem
+ * - `SDL_INIT_HAPTIC`: haptic (force feedback) subsystem
+ * - `SDL_INIT_GAMECONTROLLER`: controller subsystem; automatically
+ *   initializes the joystick subsystem
+ * - `SDL_INIT_EVENTS`: events subsystem
+ * - `SDL_INIT_EVERYTHING`: all of the above subsystems
+ * - `SDL_INIT_NOPARACHUTE`: compatibility; this flag is ignored
+ *
+ * Subsystem initialization is ref-counted, you must call SDL_QuitSubSystem()
+ * for each SDL_InitSubSystem() to correctly shutdown a subsystem manually (or
+ * call SDL_Quit() to force shutdown). If a subsystem is already loaded then
+ * this call will increase the ref-count and return.

+ *  SDL_AtomicIncRef()
+ *  SDL_AtomicDecRef()
+ *
+ * Seriously, here be dragons!

+ * There's also lots of good information here:

+ * http://preshing.com/
+ *
+ * These operations may or may not actually be implemented using

+ * Compose a custom blend mode for renderers.
+ *
+ * The functions SDL_SetRenderDrawBlendMode and SDL_SetTextureBlendMode accept
+ * the SDL_BlendMode returned by this function if the renderer supports it.
+ *
+ * A blend mode controls how the pixels from a drawing operation (source) get
+ * combined with the pixels from the render target (destination). First, the
+ * components of the source and destination pixels get multiplied with their
+ * 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,
+ * dst)` can return one of the following:
+ *
+ * - `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
+ * SDL_BlendMode enumeration.
+ *
+ * - **direct3d**: Supports all operations with all factors. However, some
+ *   factors produce unexpected results with `SDL_BLENDOPERATION_MINIMUM` and
+ *   `SDL_BLENDOPERATION_MAXIMUM`.
+ * - **direct3d11**: Same as Direct3D 9.
+ * - **opengl**: Supports the `SDL_BLENDOPERATION_ADD` operation with all
+ *   factors. OpenGL versions 1.1, 1.2, and 1.3 do not work correctly with SDL
+ *   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
+ * case.
+ *
+ * \param srcColorFactor the SDL_BlendFactor applied to the red, green, and
+ *                       blue components of the source pixels
+ * \param dstColorFactor the SDL_BlendFactor applied to the red, green, and
+ *                       blue components of the destination pixels

+ * unlike relative mode, no change is made to the cursor and it is not
+ * restrained to your window.
+ *
+ * This function may also deny mouse input to other windows--both those in
+ * your application and others on the system--so you should use this function
+ * sparingly, and in small bursts. For example, you might want to track the
+ * mouse while the user is dragging something, until the user releases a mouse
+ * button. It is not recommended that you capture the mouse for long periods
+ * of time, such as the entire time your app is running. For that, you should
+ * probably use SDL_SetRelativeMouseMode() or SDL_SetWindowGrab(), depending
+ * on your goals.
+ *
+ * While captured, mouse events still report coordinates relative to the
+ * current (foreground) window, but those coordinates may be outside the
+ * bounds of the window (including negative values). Capturing is only allowed
+ * for the foreground window. If the window loses focus while capturing, the
+ * capture will be disabled automatically.
+ *
+ * While capturing is enabled, the current window will have the
+ * `SDL_WINDOW_MOUSE_CAPTURE` flag set.
+ *
+ * Please note that as of SDL 2.0.22, SDL will attempt to "auto capture" the
+ * mouse while the user is pressing a button; this is to try and make mouse
+ * behavior more consistent between platforms, and deal with the common case
+ * of a user dragging the mouse outside of the window. This means that if you
+ * are calling SDL_CaptureMouse() only to deal with this situation, you no
+ * longer have to (although it is safe to do so). If this causes problems for

+ *
+ * The master copy of khrplatform.h is maintained in the Khronos EGL
+ * Registry repository at https://github.com/KhronosGroup/EGL-Registry
+ * The last semantic modification to khrplatform.h was at commit ID:
+ *      67a3e0864c2d75ea5287b9f3d2eb74a745936692
+ *
+ * Adopters may modify this file to suit their platform. Adopters are
+ * encouraged to submit platform specific modifications to the Khronos
+ * group so that they can be included in future versions of this file.
+ * Please submit changes by filing pull requests or issues on
+ * the EGL Registry repository linked above.
+ *
+ *
+ * See the Implementer's Guidelines for information about where this file
+ * should be located on your system and for more details of its use:
+ *    http://www.khronos.org/registry/implementers_guide.pdf
+ *
+ * This file should be included as
+ *        #include <KHR/khrplatform.h>
+ * by Khronos client API header files that use its types and defines.
+ *
+ * The types in khrplatform.h should only be used to define API-specific types.
+ *
+ * Types defined in khrplatform.h:
+ *    khronos_int8_t              signed   8  bit
+ *    khronos_uint8_t             unsigned 8  bit
+ *    khronos_int16_t             signed   16 bit
+ *    khronos_uint16_t            unsigned 16 bit
+ *    khronos_int32_t             signed   32 bit
+ *    khronos_uint32_t            unsigned 32 bit
+ *    khronos_int64_t             signed   64 bit
+ *    khronos_uint64_t            unsigned 64 bit
+ *    khronos_intptr_t            signed   same number of bits as a pointer
+ *    khronos_uintptr_t           unsigned same number of bits as a pointer
+ *    khronos_ssize_t             signed   size
+ *    khronos_usize_t             unsigned size
+ *    khronos_float_t             signed   32 bit floating point
+ *    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
+ *    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+ *                                         nanoseconds
+ *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ *    khronos_boolean_enum_t      enumerated boolean type. This should
+ *      only be used as a base type when a client API's boolean type is
+ *      an enum. Client APIs which use an integer or other type for
+ *      booleans cannot use this as the base type for their boolean.
+ *
+ * Tokens defined in khrplatform.h:
+ *
+ *    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+ *
+ *    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
+ *    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
+ *
+ * Calling convention macros defined in this file:
+ *    KHRONOS_APICALL
+ *    KHRONOS_APIENTRY
+ *    KHRONOS_APIATTRIBUTES

+ * Use this function to create a new SDL_RWops structure for reading from

+ *
+ * The `mode` string is treated roughly the same as in a call to the C
+ * library's fopen(), even if SDL doesn't happen to use fopen() behind the
+ * scenes.
+ *
+ * Available `mode` strings:
+ *
+ * - "r": Open a file for reading. The file must exist.
+ * - "w": Create an empty file for writing. If a file with the same name
+ *   already exists its content is erased and the file is treated as a new
+ *   empty file.
+ * - "a": Append to a file. Writing operations append data at the end of the
+ *   file. The file is created if it does not exist.
+ * - "r+": Open a file for update both reading and writing. The file must
+ *   exist.
+ * - "w+": Create an empty file for both reading and writing. If a file with
+ *   the same name already exists its content is erased and the file is
+ *   treated as a new empty file.
+ * - "a+": Open a file for reading and appending. All writing operations are
+ *   performed at the end of the file, protecting the previous content to be
+ *   overwritten. You can reposition (fseek, rewind) the internal pointer to
+ *   anywhere in the file for reading, but writing operations will move it
+ *   back to the end of file. The file is created if it does not exist.
+ *
+ * **NOTE**: In order to open a file as a binary file, a "b" character has to
+ * be included in the `mode` string. This additional "b" character can either
+ * be appended at the end of the string (thus making the following compound
+ * modes: "rb", "wb", "ab", "r+b", "w+b", "a+b") or be inserted between the
+ * letter and the "+" sign for the mixed modes ("rb+", "wb+", "ab+").
+ * Additional characters may follow the sequence, although they should have no
+ * effect. For example, "t" is sometimes appended to make explicit the file is
+ * a text file.
+ *
+ * This function supports Unicode filenames, but they must be encoded in UTF-8
+ * format, regardless of the underlying operating system.
+ *

+ * in an Android app's `assets`.
