Comment 5 for bug 1280382

ClearType is a sub-pixel typeface rendering, which is made for 100+ ppi color displays with RGB component sections placed exactly by three per each output pixel. ClearType requires special plotting features included in the font file from font designers. In fact, ClearType "makes text look better" only if the font designer wants it to.
On the "flat displays" that are working in wrong resolution mode, or which are connected via VGA cable (e. g., which are resampling input frames or pixel rows from original resolution step to its own), ClearType do not work properly anyway, and actually just corrupt the picture.
