// Description:

// The FontInjector DLL is a utility that allows test code to intercept any

// virtual function calls to CFont or COpenFont objects. It is used to detect

// possible virtual function calls to objects in the shared heap of the Font

// and Bitmap Server from a client process. Currently, such detection only

// works on the emulator, where code in a DLL that has been loaded by one

// process can effectively be executed from any other process.
