gecko/widget/nsGUIEventIPC.h
Rafael Ávila de Espíndola 3ae64f38a4 Bug 786148 - s/IPC/ipc/. r=ted.
This makes our builds a bit more reproducible. Without it when processing

#include "IPC/IPCMessageUtils.h

we end up in

#include "ShadowLayers.h"

which in the final XUL translates into the symbol (run nm -a to see it):

 - 00 0000   SOL ../../../../gfx/layers/IPC/ShadowLayers.h

now when some file in gfx/layers/ipc does

#include "ShadowLayres.h"

the file found is the local one with the lowercase directory name and we end up
with

 - 00 0000   SOL ../../../../gfx/layers/ipc/ShadowLayers.h
