3 This directory contains 'rasops', a set of raster operations intended to
4 replace the dev/rcons/raster stuff for both wscons and rcons. It yields
5 significantly improved performance, supports multiple depths and color.

7 The stamp_mutex used by some of the colordepths is not fully atomic. It's
8 designed to stop stamp corruption in the event that text is printed at
9 interrupt time. Even if it fails, >99% of the time text will be white on
10 black, so it doesn't really matter. Going to splhigh for each character is
11 a Bad Thing.
