+Subject: [PATCH] Fix #302: Test suite fails with freetype 2.7
+
+Actually, the test failures are not necessarily related to freetype
+2.7, but rather are caused by subpixel hinting which is enabled by
+default in freetype 2.7. Subpixel hinting is, however, already
+available in freetype 2.5 and in versions having the "Infinality"
+patch.
+
+To get the expected results in all environments, we have to disable
+subpixel hinting, what is easily done by setting a respective
+environment variable.
+
+See also:
+* https://www.freetype.org/freetype2/docs/subpixel-hinting.html
+* https://www.freetype.org/freetype2/docs/reference/ft2-tt_driver.html
