Visual and colorful representation of differences between 2.4.x and trunk

[Christophe JAILLET <ch...@wanadoo.fr>]

Hi list,

a few month ago I've posted in svg image which was a partial 
representation of differences between 2.4.x and trunk.
Now I post an updated colorful picture.

The meaning of the colors is:
    - blue:   the commit should be mergeable without conflict other than 
"CHANGES" or "docs/"

    - green:  "entry node" of the graph which does not apply cleanly
    - white:  "normal" node of the graph which does not apply cleanly
    - orange: one of the latest 25 commits, but which does not apply cleanly

    - black:  commit which gives no output when making a svn diff 
between 2.4.x and trunk. Likely a diff artifact or a partial backport


A commit marked in blue does not say that it should be backported. It 
can have some logical links with an earlier commit.
It only means that it is a good candidate to check.

Reducing the differences between 2.4.x and trunk is a good way to ease 
future backport.
If such a representation can help to synch the 2 branches, it's just fine.

Best regards,
CJ
