Tor Arvid Lund ad062d0b9d Bug 950677 - gfxIntSize -> IntSize in ipc/ directory. r=nical
(Detail: Chose to put an #include for Point.h in a header instead of a
forward declaration because a fwd decl caused an "Already defined" error
and having neither fwd decl or #include caused another compile failure
saying IntSize was undefined)
