// Background:
// OSX's default font changed in 10.9 and QT is unable to find it with its
// usual fallback methods when building against the 10.7 sdk or lower.
// The 10.8 SDK added a function to let it find the correct fallback font.
// If this fallback is not properly loaded, some characters may fail to
// render correctly.
//
// Solution: If building with the 10.7 SDK or lower and the user's platform
// is 10.9 or higher at runtime, substitute the correct font. This needs to
// happen before the QApplication is created.
