Re: A supposedly patent-free suggestion/solution to the curious subpixel rendering in Fedora

[Jud Craft <craftjml gmail com>]

When building Fedora's freetype packages, it must be easy to
independently enable Freetype's non-filtered subpixel antialiasing,
without enabling the different LCD-optimized filters that Freetype can
use.

I say this because even though you can turn on subpixel rendering in
F10, you cannot actually use any of the different LCD-optimized
subpixel filters available in the different patches.  I assumed
subpixel antialiasing was enabled, but all of the filters were not.

I may have mistakenly assumed that patent infringement applied to the
different filtering methods, as opposed to "text that just has blue
and red streaks in it." (the mere idea of your font having
nonhomogenous RGB channels).  That seems even more bizarre than just
patenting all ways of filtering the output; patenting the entire
subpixel workflow itself.

Yes, I am aware subpixel filtering is different from hinting.
