## default-256-color-palette-vector

Arguments: nil

Returns a 256-member vector of rgb objects with the colors spread out evenly. This may be useful when Windows is running in 256-color (8-bits-per-pixel) mode in order to map a higher-resolution pixmap of unknown colors into 256 colors.

To do so, call open-palette on a window and the color vector returned by this function to create a palette for that window, then apply setf to palette to assign the palette to the window, and then call copy-to-stream to copy the high-resolution pixmap to the window. The image in the window should approximate the high-resolution pixmap about as well as can be expected with 256 colors without having additional knowledge of the particular colors used in the pixmap.
