+*   raylib.shapes - Basic functions to draw 2d Shapes and check collisions
+*
+*   CONFIGURATION:
+*
+*   #define SUPPORT_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!
+*
+*   #define SUPPORT_QUADS_DRAW_MODE
+*       Use QUADS instead of TRIANGLES for drawing when possible.
+*       Some lines-based shapes could still use lines
