/**
* # CategoryAssert
*
* A helpful assertion macro!
*
* SDL assertions operate like your usual `assert` macro, but with some added
* features:
*
* - It uses a trick with the `sizeof` operator, so disabled assertions
* vaporize out of the compiled code, but variables only referenced in the
* assertion won't trigger compiler warnings about being unused.
* - It is safe to use with a dangling-else: `if (x) SDL_assert(y); else
* do_something();`
* - It works the same everywhere, instead of counting on various platforms'
* compiler and C runtime to behave.
* - It provides multiple levels of assertion (SDL_assert, SDL_assert_release,
* SDL_assert_paranoid) instead of a single all-or-nothing option.
* - It offers a variety of responses when an assertion fails (retry, trigger
* the debugger, abort the program, ignore the failure once, ignore it for
* the rest of the program's run).
* - It tries to show the user a dialog by default, if possible, but the app
* can provide a callback to handle assertion failures however they like.
* - It lets failed assertions be retried. Perhaps you had a network failure
* and just want to retry the test after plugging your network cable back
* in? You can.
* - It lets the user ignore an assertion failure, if there's a harmless
* problem that one can continue past.
* - It lets the user mark an assertion as ignored for the rest of the
* program's run; if there's a harmless problem that keeps popping up.
* - It provides statistics and data on all failed assertions to the app.
* - It allows the default assertion handler to be controlled with environment
* variables, in case an automated script needs to control it.
*
* To use it: do a debug build and just sprinkle around tests to check your
* code!

* Compose a custom blend mode for renderers.
*

*
* 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.
* 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 here.
* - **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.

* 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
*
* These may be used in function prototypes as:

* # CategoryPen
*
* Include file for SDL pen event handling.
*
* This file describes operations for pressure-sensitive pen (stylus and/or
* eraser) handling, e.g., for input and drawing tablets or suitably equipped
* mobile / tablet devices.
*
* To get started with pens:
*
* - Listen to SDL_PenMotionEvent and SDL_PenButtonEvent
* - To avoid treating pen events as mouse events, ignore SDL_MouseMotionEvent
* and SDL_MouseButtonEvent whenever `which` == SDL_PEN_MOUSEID.
*
* We primarily identify pens by SDL_PenID. The implementation makes a best
* effort to relate each SDL_PenID to the same physical device during a
* session. Formerly valid SDL_PenID values remain valid even if a device
* disappears.
*
* For identifying pens across sessions, the API provides the type SDL_GUID .

* Pixel format.
*
* SDL's pixel formats have the following naming convention:
*
* - Names with a list of components and a single bit count, such as RGB24 and
* ABGR32, define a platform-independent encoding into bytes in the order
* specified. For example, in RGB24 data, each pixel is encoded in 3 bytes
* (red, green, blue) in that order, and in ABGR32 data, each pixel is
* encoded in 4 bytes alpha, blue, green, red) in that order. Use these
* names if the property of a format that is important to you is the order
* of the bytes in memory or on disk.
* - Names with a bit count per component, such as ARGB8888 and XRGB1555, are
* "packed" into an appropriately-sized integer in the platform's native
* endianness. For example, ARGB8888 is a sequence of 32-bit integers; in
* each integer, the most significant bits are alpha, and the least
* significant bits are blue. On a little-endian CPU such as x86, the least
* significant bits of each integer are arranged first in memory, but on a
* big-endian CPU such as s390x, the most significant bits are arranged
* first. Use these names if the property of a format that is important to
* you is the meaning of each bit position within a native-endianness
* integer.
* - In indexed formats such as INDEX4LSB, each pixel is represented by
* encoding an index into the palette into the indicated number of bits,
* with multiple pixels packed into each byte if appropriate. In LSB
* formats, the first (leftmost) pixel is stored in the least-significant
* bits of the byte; in MSB formats, it's stored in the most-significant
* bits. INDEX8 does not need LSB/MSB variants, because each pixel exactly
* fills one byte.
*
* The 32-bit byte-array encodings such as RGBA32 are aliases for the
* appropriate 8888 encoding for the current platform. For example, RGBA32 is
* an alias for ABGR8888 on little-endian CPUs like x86, or an alias for
* RGBA8888 on big-endian CPUs.

/**
* Pixels are a representation of a color in a particular color space.
*
* The first characteristic of a color space is the color type. SDL understands two different color types, RGB and YCbCr, or in SDL also referred to as YUV.
*
* RGB colors consist of red, green, and blue channels of color that are added together to represent the colors we see on the screen.
* https://en.wikipedia.org/wiki/RGB_color_model
*
* YCbCr colors represent colors as a Y luma brightness component and red and blue chroma color offsets. This color representation takes advantage of the fact that the human eye is more sensitive to brightness than the color in an image. The Cb and Cr components are often compressed and have lower resolution than the luma component.
* https://en.wikipedia.org/wiki/YCbCr
*
* When the color information in YCbCr is compressed, the Y pixels are left at full resolution and each Cr and Cb pixel represents an average of the color information in a block of Y pixels. The chroma location determines where in that block of pixels the color information is coming from.
*
* The color range defines how much of the pixel to use when converting a pixel into a color on the display. When the full color range is used, the entire numeric range of the pixel bits is significant. When narrow color range is used, for historical reasons, the pixel uses only a portion of the numeric range to represent colors.
*
* The color primaries and white point are a definition of the colors in the color space relative to the standard XYZ color space.
* https://en.wikipedia.org/wiki/CIE_1931_color_space
*
* The transfer characteristic, or opto-electrical transfer function (OETF), is the way a color is converted from mathematically linear space into a non-linear output signals.
* https://en.wikipedia.org/wiki/Rec._709#Transfer_characteristics
*
* The matrix coefficients are used to convert between YCbCr and RGB colors.
