[ft] Why is hinting stronger with subpixel rendering?

[Roberto Ragusa]

It is not well understood why font render quality on Fedora Core 5 appears 
worse than on
Fedora Core 4.

I don't understand why the width of lowercase "i" or "l" is quantized to an 
exact pixel
when subpixel rendering is on and not quantized to an exact pixel when subpixel 
rendering
is off.
It should happen the opposite, shouldn't it?

happening
