* #define SUPPORT_TRIANGLES_ONLY
* Draw shapes using only TRIANGLES, vertex are accumulated in TRIANGLES arrays
*
* #define USE_DEFAULT_FONT_TEXTURE
* Draw rectangle shapes using font texture white character instead of default white texture
* Allows drawing rectangles and text with a single draw call, very useful for GUI systems!
