minor -- an integer for the required minor version
micro -- an integer for the required major version

Returns nil if the Pango library is compatible with the given version, or a string describing the version mismatch.

Checks that the Pango library in use is compatible with the given version. Compatibility is defined by two things: first the version of the running library is newer than the major.minor.micro version. Second the running library must be binary compatible with the major.minor.micro version (same major version).
