-Single file sprintf replacement.
-
-Originally written by Jeff Roberts at RAD Game Tools - 2015/10/20.
-Hereby placed in public domain.
-
-This is a full sprintf replacement that supports everything that
-the C runtime sprintfs support, including float/double, 64-bit integers,
-hex floats, field parameters (%*.*d stuff), length reads backs, etc.
-
-Why would you need this if sprintf already exists? Well, first off,
-it's *much* faster (see below). It's also much smaller than the CRT
-versions code-space-wise. We've also added some simple improvements
-that are super handy (commas in thousands, callbacks at buffer full,
-for example). Finally, the format strings for MSVC and GCC differ
-for 64-bit integers (among other small things), so this lets you use
-the same format strings in cross platform code.
-
-It uses the standard single file trick of being both the header file
-and the source itself. If you just include it normally, you just get
-the header file function definitions. To get the code, you include
-it from a C or C++ file and define STB_SPRINTF_IMPLEMENTATION first.
-
-It only uses va_args macros from the C runtime to do it's work. It
-does cast doubles to S64s and shifts and divides U64s, which does
-drag in CRT code on most platforms.
-
-It compiles to roughly 8K with float support, and 4K without.
-As a comparison, when using MSVC static libs, calling sprintf drags
-in 16K.
-
-API:
-====
-int stbsp_sprintf( char * buf, char const * fmt, ... )
-int stbsp_snprintf( char * buf, int count, char const * fmt, ... )
- Convert an arg list into a buffer. stbsp_snprintf always returns
- a zero-terminated string (unlike regular snprintf).
-
-int stbsp_vsprintf( char * buf, char const * fmt, va_list va )
-int stbsp_vsnprintf( char * buf, int count, char const * fmt, va_list va )
- Convert a va_list arg list into a buffer. stbsp_vsnprintf always returns
- a zero-terminated string (unlike regular snprintf).
-
-int stbsp_vsprintfcb( STBSP_SPRINTFCB * callback, void * user, char * buf, char const * fmt, va_list va )
- typedef char * STBSP_SPRINTFCB( char const * buf, void * user, int len );
- Convert into a buffer, calling back every STB_SPRINTF_MIN chars.
- Your callback can then copy the chars out, print them or whatever.
- This function is actually the workhorse for everything else.
- The buffer you pass in must hold at least STB_SPRINTF_MIN characters.
- // you return the next buffer to use or 0 to stop converting
-
-void stbsp_set_separators( char comma, char period )
- Set the comma and period characters to use.
-
-FLOATS/DOUBLES:
-===============
-This code uses a internal float->ascii conversion method that uses
-doubles with error correction (double-doubles, for ~105 bits of
-precision). This conversion is round-trip perfect - that is, an atof
-of the values output here will give you the bit-exact double back.
-
-One difference is that our insignificant digits will be different than
-with MSVC or GCC (but they don't match each other either). We also
-don't attempt to find the minimum length matching float (pre-MSVC15
-doesn't either).
-
-If you don't need float or doubles at all, define STB_SPRINTF_NOFLOAT
-and you'll save 4K of code space.
-
-64-BIT INTS:
-============
-This library also supports 64-bit integers and you can use MSVC style or
-GCC style indicators (%I64d or %lld). It supports the C99 specifiers
-for size_t and ptr_diff_t (%jd %zd) as well.
-
-EXTRAS:
-=======
-Like some GCCs, for integers and floats, you can use a ' (single quote)
-specifier and commas will be inserted on the thousands: "%'d" on 12345
-would print 12,345.
-
-For integers and floats, you can use a "$" specifier and the number
-will be converted to float and then divided to get kilo, mega, giga or
-tera and then printed, so "%$d" 1000 is "1.0 k", "%$.2d" 2536000 is
-"2.53 M", etc. For byte values, use two $:s, like "%$$d" to turn
-2536000 to "2.42 Mi". If you prefer JEDEC suffixes to SI ones, use three
-$:s: "%$$$d" -> "2.42 M". To remove the space between the number and the
-suffix, add "_" specifier: "%_$d" -> "2.53M".
-
-In addition to octal and hexadecimal conversions, you can print
-integers in binary: "%b" for 256 would print 100.
-
-PERFORMANCE vs MSVC 2008 32-/64-bit (GCC is even slower than MSVC):
-===================================================================
-"%d" across all 32-bit ints (4.8x/4.0x faster than 32-/64-bit MSVC)
-"%24d" across all 32-bit ints (4.5x/4.2x faster)
-"%x" across all 32-bit ints (4.5x/3.8x faster)
-"%08x" across all 32-bit ints (4.3x/3.8x faster)
-"%f" across e-10 to e+10 floats (7.3x/6.0x faster)
-"%e" across e-10 to e+10 floats (8.1x/6.0x faster)
-"%g" across e-10 to e+10 floats (10.0x/7.1x faster)
-"%f" for values near e-300 (7.9x/6.5x faster)
-"%f" for values near e+300 (10.0x/9.1x faster)
-"%e" for values near e-300 (10.1x/7.0x faster)
-"%e" for values near e+300 (9.2x/6.0x faster)
-"%.320f" for values near e-300 (12.6x/11.2x faster)
-"%a" for random values (8.6x/4.3x faster)
-"%I64d" for 64-bits with 32-bit values (4.8x/3.4x faster)
-"%I64d" for 64-bits > 32-bit values (4.9x/5.5x faster)
-"%s%s%s" for 64 char strings (7.1x/7.3x faster)
-"...512 char string..." ( 35.0x/32.5x faster!)
