+	* pdfdev.c: Fix a bug that fake-bold is not handled properly
+	in some situations as reported in
+	https://tug.org/pipermail/dvipdfmx/2019-June/000014.html.
+	When text rendering mode is changed within a text block which
+	is enclosed by q and Q, the change does not affect subsequent
+	text blocks. Current implementation of text handling is not
+	robust so we may need to reconsider it.
