commit af560c6566600a85282153ac1d04b4879abe5ce9
Author: Alastair Poole <nets...@gmail.com>
Date: Wed Sep 23 19:57:24 2020 +0100
procstats: window resource module.
The module sends messages which the theme displays. Thus, the
module requires a theme with an implemented edj script to be
useful.
Currently EFL 1.26 includes a basic text label for this...
Usage is recursive...everything under the window is included.
Rudimentary, as usual...please do something pretty...
RFC. Hopefully I didn't break the universe...again!
