Add unit cell size from the 'pixel size' element in the datasheet.
Delays are set to 2 in case a setting is entered at the very end of the
N frame, the N+1 frame will miss it and only the N+2 frame will use this
new setting.

Note that vd56g3 has a diagonal color test pattern, but does not match
any description in specified test patterns and therefore is ignored.
