97f8ec4b60 I'm not sure why, but this was necessary in order to return the 32-bit performance to the 0.0.90 baseline

e885a8bf41 Fix data corruption issues when decompressing large JPEG images and/or using buffered I/O. Specifically, decode_mcu_fast() can potentially process more than 1 MCU, so make sure there is enough space in the buffer to accommodate this case. Otherwise, the buffer pointer goes negative, and bad mojo ensues. Also, the fast decoder's method of handling unread markers doesn't make libjpeg's restart handler happy, so disable fast decode when restarts are used.
