Config to make Eclipse Juno icons and tabs look small and nice in Linux

.gtkrc-eclipse

# Create a new file in your home directory called .gtkrc-eclipse

# call eclipse with this command:
# Gtk2 forced:
# export SWT_GTK3=0
# env GTK2_RC_FILES=/usr/share/themes/<YourTheme>/gtk-2.0/gtkrc:/home/<YourUser>/.gtkrc-eclipse '/path_to_eclipse/eclipse'

# In your Eclipse directory find the file 'e4_default_gtk.css'
# In this file there's a CSS class:

# .MPartStack {
#     font-size: 11;
#     swt-simple: false;
#     swt-mru-visible: false;
# }

# And you have two possible solutions:

# 1. Change font-size to something smaller
# 2. Just comment out or remove font-size from this class (works well for me)
