-// Implements a font collection that supports interaction through sending IPC
-// messages from dwrite_font_proxy_messages.h.
-// Usage:
-//   Create a new FakeFontCollection.
-//   Call AddFont() to add fonts.
-//     For each font, call methods on the font to configure the font.
-//     Note: the indices of the fonts will correspond to the order they were
-//         added. The collection will not sort or reorder fonts in any way.
-//   Call GetSender()/GetTrackingSender() to obtain an IPC::Sender.
-//   Call Send() with DWriteFontProxyMsg_* to interact with the collection.
-//   Call MessageCount()/GetMessage() to inspect the messages that were sent.
-//
-// The internal code flow for GetSender()/Send() is as follows:
-//   GetSender() returns a new FakeSender, pointing back to the collection.
-//   FakeSender::Send() will create a new ReplySender and call
-//       ReplySender::OnMessageReceived()
-//   ReplySender::OnMessageReceived() contains the message map, which will
-//       internally call ReplySender::On*() and ReplySender::Send()
-//   ReplySender::Send() will save the reply message, to be used later.
-//   FakeSender::Send() will retrieve the reply message and save the output.
