The next included WPS using bitmap strips: 'boxes', including some cleanup, small improvements and adding missing icons. (1) All colour ports now use a backdrop to free space in the image buffer (was really near the limit on e.g. the 320x240 screen). I tried to use the same colours as the already existing 220x176 backdrop. (2) The H300 now uses a viewport instead of the frame bitmap (gets rid of the bmp and better when lines need to scroll). For simplicity it's only one viewport so that the peakmeters are now only at viewport width and the time/date info is a bit off the screen's border though. (3) Complete codec icons (I could reuse the engineer2 ones), the repeat icons and added coloured rating bitmaps. (4) Small tweeks in the virtual led, progressbar and Archos background bitmaps. (5) Correct mime-type for all.
