abc1ba07a4 [misc.roundTools] New module; move otRound() here 
Code relying on old place (fixedTools.otRound) still works.

{v,h}mtx: allow to compile/decompile even without {v,h}hhea table 
when no horizontal/vertical header table is present, we assume numberOfHMetrics == maxp.numGlyphs.
This allows to compile/decompile incomplete fonts, only containing head, maxp, hmtx, loca and glyf (or CFF),
that is the bare minimum to temporarily store glyph outline and metrics data for use with sparse/intermediate
master TTFs in varLib.

349cd94d17 [graphite] Fix for big-endian 
Make all "if sys.byteorder..." and "byteswap" be on the same line for
earsier grep verification.

use otRound when rounding visual coordinates or deltas 
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

28bb992c1f replace int(round(...)) with round(...) 
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.

[_h_m_t_x] round float values to int 
No need to issue warnings, as we don't do that either for glyf coordinates.

b1846201ba [_h_m_t_x] set longMetricFormat='Hh' as class attribute 
In theory this could be overridden with the old 'hh' struct format, though I wouldn't recommend it.

1d545b8f91 [_h_m_t_x] Read advanceWidth as unsigned short (uint16); warn on decompile if exceeds 0x7FFF; raise on compile if negative 
struct.pack will raise with `argument out of range` when trying to compile a negative integer as unsigned "H".

ca4c45681e Complety revised the XML import code: 
- use expat instead of xmlproc
- minor fixes here and there

Fixed bug in hmtx/vmtx code that only occured if all advances were equal.

FontTools now officially requires Python 2.0 or up, due to exapt and unicode.
