# PIP CANNOT DRIVE THIS ONE: the --disable-* flags are build_ext options and

# pillow probes for jpeg, tiff and the rest by trying to LINK against the build
# machine's copies.

# THREE, not one, and not four. Pillow is all extension: _imaging is the
# codec core, _imagingmath and _imagingmorph the two operations Moonraker's
# thumbnail path uses, and there is no pure-python anything behind them --
# a fallback here is not a slow Pillow, it is an ImportError. _imagingtk is
# built as well and is not counted, because it is the one that legitimately
# disappears: there is no X11 on the printer and the CPython package drops
# tkinter.
