So we now round towards +Infinity in:
- floatToFixed (which fully examplify that quotes from OT spec)
- psCharStrings: when packing floats as fixed 16.16
- t2CharStringPen: when rounding coordinates and advance widths
- subset: when rounding advance widths to compute average
- TupleVariation: rounding gvar deltas
- _g_l_y_f: when rounding coordinates: both in GlyphComponent.{x,y}
and for GlyphCoordinates.toInt()
- _h_m_t_x: for rounding horiz/vert metrics
- varLib: rounding horiz metrics and deltas
We don't need to cast to int when using the round function from py23,
as this is a backport of python3's built-in round and thus it returns
an int when called with a single argument.
Apparently Python 2 and Python 3 have different default
print precisions for floats. Or at least with my build it
is the case. As such, for example with amiri-regular.ttf
I see these annoying differences in the ttx output of the
two versions:
77203c77203
< <component ... scale="0.5999755859375" flags="0x1004"/>
---
> <component ... scale="0.599975585938" flags="0x1004"/>
That's just gross. Specially when these numbers are show to
humans, while we know that's just 0.6. The fixedToFloat()
routine in this module is smart enough to do that.
Not used yet.
