Subject: [PATCH] Add poor person's slanted shape for 'newtxtext' font

The "newtx" font package switched to TeX Gyre Termes fonts in
version 1.4 (released in TeX Live 2014). It lacks slanted shape.

In perfbook, slanted shape is not used in LaTeX sources at the
moment, but is used in page headers generated in the "book" document
style.

The switch of Times Roman clone font to "newtxtext" font made in
commit b4ad25eae241 ("future/QC: Use upright glyph for math constant
and descriptive suffix") had a side-effect of page headers to
be rendered in italic font when TeX Live 2014 or later is used.
Most notably, chapter/section numbers in page headers are rendered
upright.

This commit adds poor person's slanted shapes for roman fonts
as suggested at https://tex.stackexchange.com/questions/247539/.

This change should not have visual difference on TeX Live 2013.

Paul, please ignore this patch.
I've just observed a build error on TeX Live 2017 after this change.

Sorry for the noise.

        Thanks, Akira

[PATCH v2] Add poor person's slanted shape for 'newtxtext' font

Subject: [PATCH v2] Add poor person's slanted shape for 'newtxtext' font

The "newtx" font package switched to TeX Gyre Termes fonts in
version 1.4 (released in TeX Live 2014). It lacks slanted shape.

In perfbook, slanted shape is not used in LaTeX sources at the
moment, but is used in page headers generated in the "book" document
class.

The change of Times Roman clone font to "newtxtext" font made in
commit b4ad25eae241 ("future/QC: Use upright glyph for math constant
and descriptive suffix") had a side-effect of page headers to
be rendered in italic font when TeX Live 2014 or later is used.
Most notably, chapter/section numbers in page headers are rendered
upright.

This commit adds poor person's slanted shapes for roman fonts
as suggested in https://tex.stackexchange.com/questions/247539/.

This change doesn't have visual effect on TeX Live 2013.

Change in v2:

 Moved the definitions into the "else" clause of \IfSansSerif to avoid
 conflict with the up-to-date version of "newtxsf" math font package in
 target "1csf".

NOTE 1: Target "1csf" does not affected by the lack of slanted shape in
roman font.

NOTE 2: Target "1csf" doesn't build on TeX Live 2013.
"newtxsf" on TeX Live 2015/debian or Tex Live 2016 on Fedora 26/27 does
not conflict in v1 of this patch.
You may need to install newtxsf v1.05 [1] to see the conflict and
the resolution in v2.

    Thanks, Akira
