    @function   CTGetCoreTextVersion
    @abstract   Returns the version of the CoreText framework.

    @discussion This function returns a number indicating the version of the
                CoreText framework. Note that framework version is not always
                an accurate indicator of feature availability. The recommended
                way to use this function is first to check that the function
                pointer is non-NULL, followed by calling it and comparing its
                result to a defined constant (or constants). For example, to
                determine whether the CoreText API is available:
                    if (&CTGetCoreTextVersion != NULL && CTGetCoreTextVersion() >= kCTVersionNumber10_5) {
                        // CoreText API is available
                    }

    @result     The version number. This value is for comparison with the
                constants beginning with kCTVersionNumber.
