Fallback for source should not use sub-pixel positioning.

Current bad behavior, the code asks for a glyph that is
sub-pixel position in source space. It later renders the
glyph using the actual sub-pixel positioning in device space.

This changes the behavior to ask for an non-sub-pixel positioned
glyph in source space.
