Git history support

The history view is stripped from many graphical information, making the view useless.

Looks like Git History View needs special support from the Glance side.

I'm using MyEclipse 2013 with EGit 3.2.0 and just installed Glance.
Git History now seems to be drawn twice, once stripped of some elements and then again as it should be, but overlaid on the bugged view. Result? It's unreadable since the elements' alignments are different.

Occured the same problem with Eclipse Luna.
Glance 1.1.1 (seems the indent of label will change a little when activated a table/tree).
EGit 3.4.0.201406110918-r

Hint: close the Glance component from the code editor and Git History view will return to normal.

You are my hero, thank you for fixing this. I thought the issue was with Eclipse (https://bugs.eclipse.org/bugs/show_bug.cgi?id=493096).

Hmmm, Is it possible to fix the missing branch lines?

I have the same problem on Eclipse Mars 4.5.2 + Glance 1.1.1.
@schonarth: Could you tell us more precisely how to "close Glance component"? Actually I don't have it "opened": I always use a hotkey to search/highlight the text.
