Cross Reference: /external/pdfium/fxjs/

There are two separate wrappers for V8 here.  One is called FXJS, and
it is used by the non-XFA code.  The other is called FXJSE, and it is
used only by the XFA code.  Additionally FXJSE may request services
from FXJS to bridge the two.

Both the FXJS and FXJSE binding code needs to be replaced by something
saner, perhaps Gin or perhaps some IDL. See
  https://bugs.chromium.org/p/pdfium/issues/detail?id=716
for progress on the issue.

FXJS binds objects by sticking a pointer to a CFXJS_PerObjectData in
the V8 object's internal slot.  FXJSE binds objects by sticking a
pointer to either an actual v8 function object or a CFXJSE_HostObject
in the V8 object's internal slot, depending upon whether the object
represents (in some notion) a "class" or an "instance". Also, V8 objects
bound in one library may unexpectedly arrive at the other given a script
that's trying to mess with us.

To distinguish these cases, we use two internal slots for all bound
objects, regardless of the FXJS/FXJSE distinction.  Slot 0 is the
tag and contains either:
  kPerObjectDataTag for FXJS objects, or
  g_FXJSETagString for FXJSE Host objects, or
  One of 4 specific FXJSE_CLASS_DESCRIPTOR globals for FXJSE classes:
    GlobalClassDescriptor
    NormalClassDescriptor
    VariablesClassDescriptor
    formcalc_fm2js_descriptor

Slot 1's contents are determined by these tags:
  kPerObjectDataTag means to expect a CFXJS_PerObjectData.
  g_FXJSETagString means to expect a CFXJSE_HostObject.
  A FXJSE_CLASS_DESCRIPTOR pointer means to expect a v8 function.
