Image size not correct: Github-branch-source-plugin

[CCFenner]

I don't know is this issue can be solved in here: When I use this theme, folder and job icons are rendered with 43.2px, but icons that are generated by the github-branch-source-plugin still use 32px. This looks a bit odd.

The 32px are coded into the .icon-lg style but also in the Github png url: https://github..../avatars/u/30689?&s=32

.icon-lg {
  width: 32px;
  height: 32px;
}

Any idea how this could be fixed to have the same icon sizes?
