"Canonical developer Jamie Bennett announced in his
blog post The New UI for ARM Based Ubuntu Devices how Enlightenment
Foundation Libraries (EFL) enabled rich graphical user interfaces
even on non-3D-accelerated ARM devices.
"Enlightenment Foundation Libraries were conceived and developed
with performance in mind. Started in 2000, the current incarnation
was designed based on previous experience with Imlib and Imlib2,
libraries known to be quite fast. Over the past 10 years, the API
changed a lot to be easier to use, but the performance impact of
each and every change was carefully considered and benchmarked
using the Expedite tool.
"The most performance-critical part of EFL is definitely Evas,
the canvas (drawing) library. Fast in both software- and
hardware-accelerated environments, it always shipped with lots of
engines such as buffer, X11 (Xlib/Xcb) and XRender, but it recently
gained more interesting engines due to companies that contributed
back their work."
