// In Blink a lot of operations center around dom and Document, or around
// layout/rendering and LayoutObject. Those two headers are in turn pulling
// in large parts of Blink's other headers which means that every compilation
// unit is compiling large parts of Blink. By precompiling document.h
// and layout_object.h we only have to compile those parts once rather
// than 1500 times. It can make a large difference in compilation
// times (3-4 times faster).
// Precompiling these headers has not been found to be helpful on Windows
// compiles in 2020.
