Currently the DM_VIDEO console only supports bitmap fonts with up to 8 pixels wide glyphs. Add support for fonts with glyphs up to 32 pixels wide, as those might prove useful on high resolution screens.
This is done by expanding the glyph bits buffer to 32bits, and aligning the font data to the high bits, counting down from there. The compiler should optimise away any unneeded accesses for narrower fonts.
