- I think you've slightly misunderstood the proposal (though what you say
- is correct given the misunderstanding.)
-
- I believe the concept Todd Inglett is speaking of is that there be
- another subclass of graphic (and probably view) which would allow any
- existing ATK view to be printed simply by inserting it under a special
- view, and requesting a full update. The result of which would be a
- batch of postscript for drawing the view. This will probably be part of
- the system if we do go through with direct postscript printing.

- I actually had the quick hack done once, unfortunately I was not
- satisfied with the requirement that I have one gs process per ps inset
- (also the ability to tell gs what area of the window to use would be a
- big help). I've been meaning to send the Ghostscript folks my wish list
- for awhile now... (Another approach would be to have gs use it's
- backing pixmap, and never map it's window..., then just xcopyare from
- it's pixmap onto the view.) Unfortunately all of this violates the
- concept of window system independence. (It could be preserved if we
- used the pbm device, but that would mean putting the images out over the
- wire to the X or WM server.)
