[Sephi]

The "Volumetric Shadow Demo" is an NDS graphics hardware technology demo, which
is mainly targeted towards new NDS developers, who want to see how to activate
and utilize some of the NDS' graphics hardware features.

Spoiler: Features

* Motion blur with video capture, using only one VRAM bank, at 60 FPS
* Hardware lighting, texturing, fogging, antialiasing etc.
* Display brightness control
* Viewport scissoring (thanks to gabebear off the gbadev.org forum)
* Loading binary and text files from disk (through libfat)
* Converting .tga 24/32bit image data to 16bit nds textures
* Displaying a custom font and a text area over a background image, all loaded from disk
* Smooth touch input
* Simple frame rate counting and rendering status display
