- Yeah. For some reason I've been unable to understand, the V39/V40
- graphics.library WritePixelLine8() clears the source array after
- writing it to the destination. I, too, ran into it when my program
- worked perfectly on a CyberGraphX machine, but failed on a native
- machine. As far as I'm concerned, CGFX is right here, and the OS is
- wrong, but that doesn't help much, does it? Unfortunately the only fix
- is to do an extra copy cycle to create a temporary array to use as the
- WritePixelLine8() source.
