gfxIntSize is just a typedef of gfx::IntSize, so this is very mechanical. The only tricky part is deciding for each occurrence whether to replace it with IntSize, gfx::IntSize or mozilla::gfx::IntSize; in all cases I went with the shortest one that worked given the existing "using namespace" declarations. --HG-- extra : rebase_source : 67fd15f87222b16defa70ef795c6d77dfacf1c36
