they're not float,
the file format is one 32-bit integer object ID per
pixel.

Isn't the work around for the aliasing to clamp
the output to a 0-255 range? I haven't needed to do it yet but I think I
remember reading somewhere how those files actually are aliased but because
they are float, you don't visually see it until you clamp it.

AFAIK
no. You should probably render out RGBCMY mattes for those
things
that need object-specific mattes if you want them antialiased.
