The file size difference is due to a non-lossy compression of the lines in
the IFF framestore image (the same run-length line compression used in IFF
images since 1988). In toaster 2.0, paint saved framestores with this
compression on, but the switcher saved them w/out compression (for 722k
files every time), for faster loading. I believe the latest switcher
saves framestores with compression. I can accept your claim that
different versions have different quality, but the compression/file-size
issue really isn't related to the quality except insofar as the compressed
framestores had been converted to RGB, then re-encoded and saved as
framestores from paint (see previous post).
