If we work on having <a href="http://x.org">x.org</a> server working on the FR, wouldn't that help for whatever comes next?. At least we would have some working knowledge on how to develop drivers for X, and a team of programmers with ample knowledge on all things regarding the <a href="http://x.org">x.org</a> Server.<br>
<br>I mean, the thing is modularized. Is it not simpler to just replace the glamo driver with the [whatever\] driver?<br><br><div class="gmail_quote">On Mon, Nov 17, 2008 at 11:48 AM, Iain B.

<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I have implemented an image display script on the FR that demonstrates<br>
smooth scroll in the form of dragging the image about the screen. Works<br>
for fairly large images (colour weather maps of North America). The<br>
application uses the FLTK tool kit with double buffering through X.<br>
