[x] Don't buffer if !_canBacktrack https://github.com/benjamin-hodgson/Gutenberg/commit/e487831e329a74d1f1c48794f97ba277430dddbe
[ ] Put _lineBuffer and _stack in pooled memory
- this will only have benefit if Render is called multiple times in an app lifespan. Might not be worth?
[x] Make LayoutInstruction a struct https://github.com/benjamin-hodgson/Gutenberg/commit/a7bb38072cbb5dc11bcc18707daa4f0f199aea34
[x] Pool StackItem where possible? https://github.com/benjamin-hodgson/Gutenberg/commit/c06a7fea28e0f1f581fecae58eaec8705616ce62 https://github.com/benjamin-hodgson/Gutenberg/commit/5edda8123343d3785051ab885fc4414ef7556e70 https://github.com/benjamin-hodgson/Gutenberg/commit/4718dcc23a2938a00bb963c552aae9da52e44ae0
[x] Use a cached string in PlainTextDocumentRenderer.WhiteSpace https://github.com/benjamin-hodgson/Gutenberg/commit/ff08cb303ee0f6a825f81bdd37f11c05eb223117
