Description
See the following capture:

In a stack we have nodes from both `xul.pdb` and `DWrite.pdb`. At other places we have other libraries like `user32.pdb` or `ExplorerFrame.pdb`.
Ideas:
* change the background color for different libraries
* change the color for the lib name text
* add an horizontal colored line at the node edge
