The Enlightenment Foundation Libraries (EFL) are a set of graphics
libraries that grew out of the development of Enlightenment. The
libraries are meant to be portable and optimized to be functional even
on mobile devices such as smart phones and tablets. They provide both
a semi-traditional toolkit set in Elementary as well as the object
canvas (Evas) and powerful abstracted objects (Edje) that you can
combine, mix and match, even layer on top of each other with alpha
channels and events in-tact. The library supports 3D transformations
for all objects and more.
