One big issue in porting applications over to iliad is the e-ink screen takes time to update and partial screen update usually won't work well.
I know there is a hacked X11 lib that would ease the porting effort, but just curious on the "proper" way of handing screen updates with iLiad.
Which function to use for full or partial screen updates?
Do you always have to use XSync? I see examples of using it from the ipdf source.
Why are some functions like gtk_widget_send_expose not working?
What kind of modifications do you do when porting another X11/GTK app?
I'm asking because I'm interested in porting
Xournal, a note scribbling tool with antialiased lines. Any help is greatly appreciated!
