[sldev] Plausibility of 16-bit sculpts?

[Dahlia Trimble]

Wouldn't 16 bit textures be converted to the same floating point vertex data
as the current 8 bit ones? I'm having a difficult time trying to understand
why additional precision of the source texture would reduce frame rates. It
seems all it would do is enable the artist to specify vertex position with a
higher level of precision, it would not add more vertices or require a
higher precision floating point number in the resulting sculpt mesh.
Now it probably would slow down downloads of the textures somewhat.
