Further texture color tweaks

Tweaked all OSDfooFO.png to match closer the blue color of confluence.
All these really had far too different shades

Tweaked the Scrollbar V/H Focus to match closer

Tweaked the OSDProgress outline to be yet slightly fainter still.

All these textures were probably done at different times and different
people as such palettes really were not same, and without source files
its hard to do a perfect job.
