Note this patch exchanges in NativeThemeQt.{h.cpp} only nsMargin and nsSize against nsIntMargin and nsIntSize, respectively, while nsRect remains unchanged due to the inclusion of gfx/public/nsITheme.h In nsWindow{h,cpp} all occurrences of nsRect and nsPoint are exchanged against nsIntRect and nsIntPoint, respectively. Tested the patch by building with --enable-default-toolkit=cairo-qt
