PTAL

[Lei Zhang, 2016-08-26 18:19:46]

If this is just straight up putting the code back, then lgtm.

Don't bother changing pdfium.gyp. I'm trying to delete all the GYP files today.

Is all of the code in these files required by the viewer or only some of it? Can
we split these files apart like the rest of the code in core/fpdfdoc and for the
stuff that is required, add API's into public/ so we can keep track of what's
needed?

This is only a revert CL. pdfium:568 has been filed requesting public API. As
far as I can tell, the classes/structs declared at fpdf_tagged.h are being used,
but the ones at tagged_int.h are not. However, tagged_int.h is being imported
once (possibly for no good reason).
