RandR 1.3 support projection ?

Dear all,

    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.

    I have tested the matrix (1,0,0,0,1,0,0,0.5,0) on Intel platform.
And it's not supported.

Is there something wrong with the projection matrix?

    Thanks!

 

Best wishes,

Gordon
