Hey list,
I'm trying to clean up the above function somewhat and wonder about a
few things:
```
scaler.face = face;
scaler.x_scale = size->metrics.x_scale;
scaler.x_delta = 0; /* XXX: TODO: add support for sub-pixel
hinting */
scaler.y_scale = size->metrics.y_scale;
scaler.y_delta = 0; /* XXX: TODO: add support for sub-pixel
hinting */
scaler.render_mode = FT_LOAD_TARGET_MODE( load_flags );
scaler.flags = 0; /* XXX: fix this */
```
What exactly is this subpixel hinting and what is needed to support it?
What about the flags needs to be fixed?
```
#ifdef FT_OPTION_AUTOFIT2
/* XXX: undocumented hook to activate the latin2 writing system
*/
if ( load_flags & ( 1UL << 20 ) )
options = AF_STYLE_LTN2_DFLT;
#endif
```
Is this used in any capacity?
```
/* for mono-width fonts (like Andale, Courier, etc.) we
need */
/* to keep the original rounded advance width; ditto for
*/
/* digits if all have the same advance width */
[...]
```
Why is this ifdef'ed out? Why is the second block below that ifdef'ed
out? Can they be removed?
