Hi Tadziu,

This is my fault. I wrote "pdf: pdfpic" to mimic the behaviour of .PSPIC, 
render image down from current point, not realising (until now!) that "ps: 
import" renders the image up from the current point. This difference in 
behaviour is somewhat masked because the higher level interfaces, .PSPIC and 
.PDFPIC, both render the image downwards.

The above difference means this works for pdf:-

  .char \[gnu] \v'-9p'\X'pdf: pdfpic GNU-head-small.pdf -L 10p'\h'10p'
  A GNU head \[gnu] image.

There may be an argument for adding "pdf: pdfpicup" to gropdf to render 
upwards, for this type of situation where the image is intended to sit on the 
baseline.

Cheers
