+*
+*   raylib [text] example - 3d drawing
+*
+*   Example complexity rating: [★★★★] 4/4
+*
+*   NOTE: Draw a 2D text in 3D space, each letter is drawn in a quad (or 2 quads if backface is set)
+*   where the texture coodinates of each quad map to the texture coordinates of the glyphs
+*   inside the font texture
+*
+*   A more efficient approach, i believe, would be to render the text in a render texture and
+*   map that texture to a plane and render that, or maybe a shader but my method allows more
+*   flexibility...for example to change position of each letter individually to make somethink
+*   like a wavy text effect
+*
+*   Special thanks to:
+*        @Nighten for the DrawTextStyle() code https://github.com/NightenDushi/Raylib_DrawTextStyle
+*        Chris Camacho (codifies - http://bedroomcoders.co.uk/) for the alpha discard shader
+*
+*   Example originally created with raylib 3.5, last time updated with raylib 4.0
