[OpenType] Hinting question |

(If there is a better forum in which to post this question, please let me
know.)
My understanding is that TrueType hinting takes the point size, device
resolution, and font transform as separate components. The point size
indicates the optical size of the font, and is used to customize the
outline of the glyphs for the intended optical size (control serifs, stem
thickness). The device resolution and transform are used to control
rasterization, to avoid unequal stem widths and so on.
In practice, do type designers, and rasterizers, make use of these
distinctions? Or do type designers seldom perform optical size
adjustments, and rasterizers generally roll the data into one transform
matrix? If so, then it is not possible to distinguish the point size from
the 'zoom factor', or to identify the actual intended physical size of the
font. Is this a problem?
