/* Notes on the heuristics used here:
much of the complexity here comes from the desire to support
Chrome apps.
From https://bugzilla.gnome.org/show_bug.cgi?id=673657#c13
Currently chrome sets WM_CLASS as follows (the first string is the 'instance',
the second one is the 'class':
For the normal browser:
WM_CLASS(STRING) = "chromium", "Chromium"
For a bookmarked page (through 'Tools -> Create application shortcuts')
WM_CLASS(STRING) = "wiki.gnome.org__GnomeShell_ApplicationBased", "Chromium"
For an application from the chrome store (with a .desktop file created through
right click, "Create shortcuts" from Chrome's apps overview)
WM_CLASS(STRING) = "crx_blpcfgokakmgnkcojhhkbfbldkacnbeo", "Chromium"
The .desktop file has a matching StartupWMClass, but the name differs, e.g. for
the store app (youtube) there is
.local/share/applications/chrome-blpcfgokakmgnkcojhhkbfbldkacnbeo-Default.desktop
with
StartupWMClass=crx_blpcfgokakmgnkcojhhkbfbldkacnbeo
Note that chromium (but not google-chrome!) includes a StartupWMClass=chromium
in their .desktop file, so we must match the instance first.
Also note that in the good case (regular gtk+ app without hacks), instance and
class are the same except for case and there is no StartupWMClass at all.
