This allows to select, say, the subpixel hinting mode at runtime for a given
application.
If LONG_PCF_NAMES port's option was enabled, the PCF family names may include
the foundry and information whether they contain wide characters. For example,
"Sony Fixed" or "Misc Fixed Wide", instead of "Fixed". This can be disabled at
run time with using pcf:no-long-family-names property, if needed. Example:
FREETYPE_PROPERTIES=pcf:no-long-family-names=1
How to recreate fontconfig cache with using such environment variable,
if needed:
# env FREETYPE_PROPERTIES=pcf:no-long-family-names=1 fc-cache -fsv
The controllable properties are listed in the section "Controlling FreeType
Modules" in the reference's table of contents
(%%DOCSDIR%%/reference/site/index.html, if documentation was installed).
