This is not the most most efficient way to store truecolor data in
Euphoria. A Euphoria sequence has 20 bytes of overhead, and it always
stores at least 4 bytes for each element, so you're effectively wasting
29 bytes for *every* truecolor pixel.

Your best bet for fast graphics is to poke pixel data into a memory buffer
acquired with allocate, then copy that memory into video ram. Of course,
then your new bottleneck is how fast you can move that memory across the
bus. Full-screen truecolor images consume a good chunk of memory and
limitations of hardware come into play. AGP cards have a speed advantage
over PCI, and PCI is faster than ISA.

Most helpful in my opinion would be wrappers to DirectX or OpenGL, where
we can take advantage of the hardware-accelerated operations on the
graphics hardware and let the cpu do more work on actual gameplay.

p.s. some of you may think this kind of talk is a little "out of
character" for me, having written Neil and all...
