ventosusAlthoug freeader should be a minimal reader, there must be some way to navigate between books, e.g. a kind of menu structure.
This menu structure will also be prerendered pixel data, like the books themselves.
I use Edje from the Enlightenment Foundation Libraries (EFL) as underlying theming and layouting engine.

Why Edje? I have built other things on top of the EFL, know them well and like them a lot.

With Evas (the EFL canvas library) you can draw to pretty much everying (X11, openGL, Wayland, framebuffer, pixel buffer, ...). Here I draw to a pixel buffer and then compress it with JBIG1.
By using Edje, the menu structure can be themed to the last nut. I've experimented a bit and below you can see two screenshots of a sketch of a simple menu theme.The menu structure will have limited capabilities, e.g. navigating a directory tree and loading a given book.
I have just uploaded my repository with the current toolchain.
