/*

* Really basic sample for the NDS.

*

* Fills a rectangle increasingly smaller of random color every time a

* button (a, b, x, y) is pressed.

*

* The behaviour whether SDL is compiled with HW support or not (see

* USE_HW_RENDERER in Makefile.ds).

*

* In framebuffer mode, the old rectangles stay because the screen has

* not been cleared.

*

* In accelerated mode, old the last rectangle is visible.

*

* No text is displayed.
