// stb_easy_font.h - v1.1 - bitmap font for 3D rendering - public domain
// Sean Barrett, Feb 2015
//
// Easy-to-deploy,
// reasonably compact,
// extremely inefficient performance-wise,
// crappy-looking,
// ASCII-only,
// bitmap font for use in 3D APIs.
//
// Intended for when you just want to get some text displaying
// in a 3D app as quickly as possible.
//
// Doesn't use any textures, instead builds characters out of quads.
//
// DOCUMENTATION:
//
// int stb_easy_font_width(char *text)
// int stb_easy_font_height(char *text)
//
// Takes a string and returns the horizontal size and the
// vertical size (which can vary if 'text' has newlines).
//
// int stb_easy_font_print(float x, float y,
// char *text, unsigned char color[4],
// void *vertex_buffer, int vbuf_size)
//
// Takes a string (which can contain '\n') and fills out a
// vertex buffer with renderable data to draw the string.
// Output data assumes increasing x is rightwards, increasing y
// is downwards.
//
// The vertex data is divided into quads, i.e. there are four
// vertices in the vertex buffer for each quad.
//
// The vertices are stored in an interleaved format:
//
// x:float
// y:float
// z:float
// color:uint8[4]
//
// You can ignore z and color if you get them from elsewhere
// This format was chosen in the hopes it would make it
// easier for you to reuse existing vertex-buffer-drawing code.
//
// If you pass in NULL for color, it becomes 255,255,255,255.
//
// Returns the number of quads.
//
// If the buffer isn't large enough, it will truncate.
// Expect it to use an average of ~270 bytes per character.
//
// If your API doesn't draw quads, build a reusable index
// list that allows you to render quads as indexed triangles.
//
// void stb_easy_font_spacing(float spacing)
//
// Use positive values to expand the space between characters,
// and small negative values (no smaller than -1.5) to contract
// the space between characters.
//
// E.g. spacing = 1 adds one "pixel" of spacing between the
// characters. spacing = -1 is reasonable but feels a bit too
// compact to me; -0.5 is a reasonable compromise as long as
// you're scaling the font up.
//
// LICENSE
//
// See end of file for license information.
//
// VERSION HISTORY
//
// (2020-02-02) 1.1 make everything static so can compile it in more than one src file
// (2017-01-15) 1.0 space character takes same space as numbers; fix bad spacing of 'f'
// (2016-01-22) 0.7 width() supports multiline text; add height()
// (2015-09-13) 0.6 #include <math.h>; updated license
