Yes, it should be possible handle both with one drawing function.

One limitation of bitmap_plot, and also display_bitmap is, that it does 
not work for back&white displays, even if the latter function is used 
somehow for black&white display, e.g. with ugly hacks for MCC200. I 
would like to have generic drawing functions for 1, 8 and 16 bpp.

Wolfgang.
