-// 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.
-//
-// The same thing happened with 10.10. .Helvetica Neue DeskInterface is now default.
-//
-// 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.
