One of the new features in DX10 is support for packed monochrome
bitmaps in hardware. They are used to draw fonts at a large point size
- like 50pt and then they are filtered down to the desired point size
via a good filter (i forget which one, but not a simple linear one,
maybe trilinear?). The same 50pt font is used to dynamically generate
all of the small point fonts.
The fonts are drawn 3X as wide as you want. After filtering the 3x
width is collapsed down into a single pixel which converts to to a
three component alpha channel. The three components correspond to the
RGB pixels of LCD sub-pixel rendering.
There is a paper about this on the Microsoft site.
Since this would seem to be impossible, it would be a very interesting
paper to read.
