The format is the same. Using an LCD rendering mode triples the
horizontal buffer length.

If this flag isn't set, you'll get, for example, instead of a 5-pixel
buffer (without LCD rendering)
ABCDE
a buffer which triples each pixel value:
AAABBBCCCDDDEEE
According to the information in the web, patents on the ClearType idea
itself aren't valid due to prior art. However, patents on the LCD
colour filtering used in Windows are definitely valid (well, if you
live in a country where software patents are valid).
