- cputc was drawing at the wrong position, therefore one line had to be removed as a workaround. - chline, cvline were drawing one pixel to large lines. - cclear was drawing an in both directions one pixel to big rect. - the cursor was drawn at wrong times at wrong places in a wrong size. git-svn-id: svn://svn.cc65.org/cc65/trunk@5874 b7a2c559-68d2-44c3-8de9-860c34a00d81
