Hello everybody out there using Org-mode,

Some time ago, Eric Fraga had posted a script for generating Gantt charts directly out of Org-mode which is very helpful.
Some project management software allows to follow the progress of tasks by staining a proportional part of the rectangle for a certain task in relation to its completion percentage in green and the rest in red.
This allows easier evaluation of a project's current status.
I added this feature to Eric Fraga's code and would like to post it here for discussion. It would be great if it could be somehow added to Org-mode.

Thank you for making Org-mode such a good piece of software,
Julia
