Make the classic_statusbar.sbs more classic. Icons, position of numbers, charging animation (only tested on a colour display so far), volume as before but gets a 'clipping' icon on targets that allow more than 0dB, add channels indicator in the rec screen. The only difference on swcodec should be the disk activity indicator on flash targets (for now). On hwcodec there are small differences in the recording screen - quality display is simply using the system font (no wasting another bitmap on a slightly less taller Q), frequency uses icons now (keeping the differences between the sbs files smaller and with the small 'k' it's easier to understand, but debateable). Since the animation makes use of the viewport colour (shades) parameters, a classic_statusbar.grey.sbs was needed - reusing the colour one didn't work correctly anyways. The difference between Recorders (RTC) and Ondios (disk activity) is achieved through the 112x64x1.sbs file itself.
