Author: bde Date: Wed Apr 24 16:03:35 2019 New Revision: 346641 URL: https://svnweb.freebsd.org/changeset/base/346641 Log: Avoid hiding and unhiding the mouse cursor when copying bitmaps to the screen. Instead, copy a merged bitmap 1 line at a time. This fixes flashing of the cursor and is faster in all modes (especially in planar modes).
