it's easier to get an accurate port. ie text is 1:1 the same for every
character, glyph, pixel, spacing, kerning etc. also you get the character
querying for free. :)

ok. check timers in ecore work. check ilders, and idle enterers work. last time
i played with directfb the real problem was dfb didn't have select() support.
this means i couldn't sit in a select and wait on fd's and use it as a timer
system. i'd need to have dfb's event call wait until a timeout and have a
separate thread do select() and then post a fake "wake up" event to the dfb
event queue to wake up the dfb "next event" call. this was a bit of a PITA.
ecore_evas uses idle handlers to render with evas. edje uses ecore_evas's
pre_render and post_render calls to freeze then thaw the edje - which basically
means the edje wont update change or be recalculated as long as its frozen. it
could be this? (which would lead back to idle enterers not working and thus
timers and idlers too). check on this. you also need to build the eet image
loader in evas - maybe you didn't build it? try these things... maybe it'll get
you up and running.
