I've dug through the code and made copy/paste/rename adjustments 
everywhere it seemed reasonable (first day with c-code...). This will 
probably more show how lost I am than anything else, but below are the 
diffs for all files I've been poking around (don't think I forgot any). 
I think my main issue is that I have no clue how to connect the static 
that I made (SANE_EPSON_CAP_FULL_SENSOR_IN_TPU) to what is being sent in 
the scanner in "define esci_set_full_sensor(s,v)            e2_esc_cmd( 
s,(s)->hw->cmd->set_full_sensor, v)". That is to give set_full_sensor 
the value of SANE_EPSON_CAP_FULL_SENSOR_IN_TPU.
