Fix bug 702079: SEGV with clist and PCL caused by wrong color in images.
The clist_image_plane_data function was called with the dev_color for a band
being type <pattern> when the image had type <pure>, but the code was not
calling cmd_put_drawing_color to update the bands for the image because uses_color
was false. Add rop3_uses_S(pgs0>log_op) as well as (||) rop3_uses_T(pgs->log_op)
when CombineWitColor is true.
Note that extra calls to cmd_put_drawing_color before an image are low cost
and do nothing if the current device color is already the same.
