*
*   rtext - Basic functions to load fonts and draw text
*
*   CONFIGURATION:
*       #define SUPPORT_MODULE_RTEXT        1
*           rtext module is included in the build
*
*       #define SUPPORT_FILEFORMAT_FNT      1
*       #define SUPPORT_FILEFORMAT_TTF      1
*       #define SUPPORT_FILEFORMAT_BDF      0
*           Selected desired fileformats to be supported for loading. Some of those formats are
*           supported by default, to remove support, #define as 0 in this module or your build system
*
*       #define MAX_TEXT_BUFFER_LENGTH   1024
*           Text functions using static buffer max size
*
*       #define MAX_TEXTSPLIT_COUNT       128
*           TextSplit() function static substrings pointers array (pointing to static buffer)
*
*       #define FONT_ATLAS_CORNER_REC_SIZE  3
*           On font atlas image generation [GenImageFontAtlas()], add a NxN pixels white rectangle
*           at the bottom-right corner of the atlas. It can be useful to for shapes drawing, to allow
*           drawing text and shapes with a single draw call [SetShapesTexture()]
*
*   DEPENDENCIES:
*       stb_truetype  - Load TTF file and rasterize characters data
*       stb_rect_pack - Rectangles packing algorithms, required for font atlas generation
