# I don't think LMS renderer handles properly screens other than 32 pixels. It
# seems that all we get is a 32 pixel-tall data with anything else padded to 0
# i.e. if we try 64 pixels height, bytes 0..3 and 4..7 will contains the same 
# pattern than the 32 pixels version, where one would have expected bytes 4..7
# to be empty
