Author: jkim Date: Wed Sep 22 22:16:48 2010 New Revision: 213040 URL: http://svn.freebsd.org/changeset/base/213040 Log: MFC: r212806 Rework r210248. Although it fixed most of problems, it did not fix one particular edge case where X-axis resolution is not multiple of font width. Now we just advance enough scan lines, then deduct a partial scan line. It is more intuitive than the previous code. Apply the same wisdom to EGA and VGA planar renderers for consistency.
