- Changed WI_drawPercent() when wi_percents is false so that the total display is optional, and it formats it like Heretic's intermission, with a slash and a fixed-width right column. - Font is no longer a property of the screen object. Pass the font to DrawText and DrawChar directly instead. - Doom's intermission characters are now collected together as a font so they can be colorized. SVN r1294 (trunk)
