In RandR 1.3 introduction ppt, it’s said that RandR 1.3 support
projection and the transformation matrix is (1,0,0,0,1,0,0,1/d,0). That means
that if the source ordinate is (x, y), the destination ordinate is (d*x/y, d). It’s
the projection value on the line y=d. The CRTC contents will become a line
after projection.<o:p></o:p></span></font></b></p>

not supported.<o:p></o:p></span></font></b></p>
