PgVersion.check

Checks that the Pango library in use is compatible with the given version. Generally you would pass in the constants PANGO_VERSION_MAJOR, PANGO_VERSION_MINOR, PANGO_VERSION_MICRO as the three arguments to this function; that produces a check that the library in use at run-time is compatible with the version of Pango the application or module was compiled against. Compatibility is defined by two things: first the version of the running library is newer than the version required_major.required_minor.required_micro. Second the running library must be binary compatible with the version required_major.required_minor.required_micro (same major version.) For compile-time version checking use PANGO_VERSION_CHECK(). Since 1.16
