CabbieV2 had an FM screen only for the 160x128 and 128x128 greyscale
targets. Add one for 400x240, laid out like its WPS: station art and
names where the album art and track info are, the frequency in the
progress bar, Scan/Preset, MHz and Stereo/Mono below it, and hold,
battery, volume and signal strength along the bottom.
Both screens share one backdrop, its header bar empty: each draws its
label, NOW PLAYING or FM RADIO, in Helvetica Bold rather than having it
painted into a backdrop of its own. The shuffle and repeat
placeholders, painted into the old WPS backdrop, are images drawn
while those are off.
