+* Hello Triangle example, made by Lectem
+*
+* Draws a white triangle using the 3DS GPU.
+* This example should give you enough hints and links on how to use the GPU for basic non-textured rendering.
+* Another version of this example will be made with colors.
+*
+* Thanks to smea, fincs, neobrain, xerpi and all those who helped me understand how the 3DS GPU works
