/*

 * 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.
