Add lightweight visual indication for numbers.

This change adds lightweight visual hints of alternate numeric characters on the top row - e.g. having a light gray '1' on the upper right corner of letter 'q'

Note that MDPI resources are tentative (the same as HDPI for now, until we get fixed MDPI visual assets).
