This has two major advantages: - Removal of a maze of global variables and distinction of cases from the sprite loading routines, which weren't directly related to the loading process in the first place - NewGRF actions no longer occupy sprite slots - for example when using DBSetXL this saves about 2000 slots! (you could regard this as a bug fix) If i didn't make a major mistake this change should have no negative effect on NewGRF support, please test!
