"Luck - not a factor." (trivia quiz: what movie did i just quote?)
And before people start getting strange ideas; there is nothing magical about shaders... Anyone can pick up a book and learn how to code them, provided they are willing to spend a tiny bit of time. No need for ultra fancy video hardware either...
Basically we want to move graphics rendering where it belongs - to the video hardware. The old shifter code uses a bunch of lookup tables for planar to chunky conversion, which does not really translate or scale well to modern "pc" hardware. And OS X does all this sweet compositing on the GPU already, which kills 2D performance on the CPU as it forces a lot of data to be moved back and forth to video RAM.
SDL needs to do something about that, maybe 1.3 does but i dont know how that is progressing. Perhaps Patrice knows? Compositing is not uncommon in other operating systems anymore either, and so for everyones sake we need to stop wasting bus cycles and make some progress...
/Kaare (waiting for Hatari mercurial repository to turn sane again - #defines are _not_ for symbol remapping.)

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
