media-libs/freetype-2.4.10-r1 adds an lcdfilter USE flag that does *not* control LCD "filtering" (sub pixel rendering). Freetype always supports that since a few versions now. Building with "-lcdfilter" does not disable that feature. The USE flag should be renamed to reflect what it is. It is not a flag that enables/disables Freetype SPR. It's a flag that replaces Freetype's implementation with a third-party one. Please name the flag "infinality" or whatever. *Not* "lcdfilter".
I agree that the infinality useflag is more precise, so I have changed it.
