I'll comment on libraries that might not be clear:

These three are needed by GTK. Pango is (basically) the "font backend", 
Cairo is the drawing backend while ATK is needed to provide 
accessibility features

Pango uses Cairo as a backend as well.

Pango uses FreeType to retrieve font informations (see next library).

This is needed to look for fonts installed in the system.

Needed by glib2.

Lowlevel graphic operations, needed by cairo (can be compiled statically 
as well)

Seems that direct FrameBuffer rendering was enabled for GTK or Cairo... 
so normally not needed.

I don't know about these two.

> libpng12.so.0 => /lib/libpng12.so.0 (0x00007fed232b0000)

This is needed by Cairo.

I don't know why this one is in there

This is a XML library and used by fontconfig.
