libesci_interpreter_gt_f720_342::libesci_interpreter_gt_f720_348 at 0xdf74: the
4

binary blob esfw8b.bin is searched either in /usr/share/esci/ or in
5

$ESCI_FIRMWARE_DIR. But since this library is to be used wia libsane.so in
6

every binary in the system, we can't wrapProgram the relevant executables to

set this environment variable. Instead, we patch iscan to set this variable

before loading libesci-interpreter-gt-f720.so.
