Behdad Esfahbod a71b9c8579 Disable 'cswh' by default except for Arabic shaper
That better matches OpenType spec.  Note that we enable it for all
Arabic-shaper scripts.  Ie. we enable it by default for Syriac too,
but the SyriacOT spec does not require it.  I think this is a more
useful compromise than special-casing for Arabic script alone.

Behdad Esfahbod 3286fc0e9a Let hb_shape() guess script and direction...
- Rename HB_SCRIPT_INVALID_CODE to HB_SCRIPT_INVALID

- Add HB_DIRECTION_INVALID

- Make hb_script_get_horizontal_direction() public

- Make hb_shape() guess script from buffer text (first non-common
  non-inherit script) if buffer script is set to HB_SCRIPT_INVALID (this
  is NOT the default.)

- Make hb_shape() guess direction from buffer script if buffer direction
is set to HB_DIRECTION_INVALID (this is NOT the default.)

- Make hb-view.c set INVALID script and direction on the buffer.

The above changes are meant to make hb-view fairly useful for uni-script
uni-direction text.  The guessing behavior however is NOT the default of
hb_shape() and must be asked for explicitly.  This is intended, because
the guess is not a suitable substitute to full-fledged bidi and script
segmentation.  It's just a testing tool.

Behdad Esfahbod ee8aaf976a Fix arabic shaping of LTR text
We should ensure-direction before doing any complex work.  The only
exception is mirroring that needs to see the original / final direction,
not the native.  Handle that.

Behdad Esfahbod bd7378b2ef Massage mask setting a bit more
Still finding the exact correct way the masks should be set.

Behdad Esfahbod 39dede9fff Make sure boolean features always use value=1
Previously boolean features turned on the entire feature mask.  This is
wrong if feature is Alternate and user has provided values bigger than one.
Though, I don't think other engines support such corner cases.
