This won't work. The original code increments 'fb' and 'bmap' pointers
in the inner for loop. Using this function in the inner loop won't
increment the pointers as needed, as these will only be incremented in
the function itself (as local variables).
Also please use a different name for the macro, CONFIGURATION_FB_PUTB
isn't a descriptive name. FB_PUT_PIXEL or similar perhaps?
Thanks,
Anatolij
