Doh! Thanks for the correction.
The general point still holds though, right? All of those services need to
be provided in some layer between the framebuffer and AbiWord, so a more
accurate comparison would be:
framebuffer <--> glue1 <--> GDK <--> GTK <--> AbiWord
framebuffer <--> glue2 <--> AbiWord
The practical question is how much work implementing glue1 saves you
relative to implementing all of glue2. There's quite a large gap to cover
between ...
... what AbiWord expects (services provided by a modern GUI)
... what a raw framebuffer provides (almost nothing)
I certainly didn't mean to trivialize what it takes to get GDK running on a
framebuffer, but I do *hope* it'd save you at least some work somewhere that
GTK does for you. :-)
