/*

* 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.
