Titlebutton hover animation fix
This CL fixes a bug in the animation of the titlebuttons in the
titlebar. Transitioning between ':hover' and ':not(:hover)' states caused an
artifact.
The CL adds a fully transparent version of the background image for the
default state that allows GTK to transition between the two states seemlessly.
The CL also renames the two background images to clarify their use.
