Use the call glDrawPixels()

An easy way is to give the bottom channel a pfScene that only contains
geometry for a quad in the XY-plane. And this quad is textured with the
required image. Give the pfChannel an ortho view frustum that exactly
views this quad, and draw the things you want to draw after calling
pfDraw().
