"Function used to draw a rsync progress bar in mode-line.
Function is called with three args: PROCESS, PERCENT, INFO.
PROCESS is the rsync process in use, it's name is displayed before the progress
bar, it is useful to display it to distinguish the different processes running
e.g. rsync1 rsync2 etc...
PERCENT is the current percentage of data sent to the progress bar.
INFO is what is displayed after the progress bar according to
`helm-ff-rsync-progress-bar-info'.
Currently Helm provides two functions to draw the progress bar:
- The default progress bar which use the whole height of mode-line and print
colored spaces to mimic a progress bar.
- The SVG based progress bar which use the external library svg-lib (you will
have to install it to use this function) and needs emacs to be compiled with svg
support."
